Fig. 2 is the schematic diagram of the switched mode converter integrated circuit of the embodiment of the present invention.As shown in Fig. 2, described be applied to
The Integrated circuit IC for constructing switched mode converter includes power switch M1, rectifier switch M2, ON-OFF control circuit SLC and mode
Selection circuit MODE.Wherein, power switch M1 is connected between voltage input end VIN and intermediate ends LX.Rectifier switch M2 connection
Between intermediate ends LX and ground terminal.The connection type of power switch M1 and rectifier switch M2 make the two be suitable for building voltage-dropping type
The switched mode converter of topology.ON-OFF control circuit SLC is connected by the control terminal of a three state buffer T1 and power switch M1
It connects, while being connect by a buffer BUF1 with the control terminal of rectifier switch M2.Three state buffer T1 can be according to enable end
Signal switch between working condition or high impedance status (off state).Mode selection circuit MODE is suitable in selection signal
SEL changes the control terminal voltage of power switch with the output of ON-OFF control circuit,
When selection signal is the second state (such as high level), control power switch is switched to pass-through state.
In circuit shown in Fig. 2, mode selection circuit MODE controls tri-state when selection signal SEL is first state
Buffer T1 is switched to working condition, and the control signal from ON-OFF control circuit SLC is enabled to pass through three state buffer T1
It is applied to power switch M1, meanwhile, the control signal from ON-OFF control circuit SLC can be applied to rectifier switch by BUF1
M2.Power switch M1 and rectifier switch M2 is according to the control alternate conduction of ON-OFF control circuit SLC and shutdown, so that switching mode
Converter exports stable current or voltage.As a result, in the flrst mode, power switch M1 is opened as the master of switched mode converter
It closes and uses.For mode selection circuit MODE when selection signal SEL is the second state, control three state buffer T1 is switched to high impedance
State, thus influence of the mask switch control circuit SLC for power switch, meanwhile, the output of charge pump CP is applied to function
Rate switch M1, so that power switch M1 is switched to pass-through state.Meanwhile rectifier switch M2 is controlled by ON-OFF control circuit
SLC or mode selection circuit MODE is in an off state when selection signal SEL is the second state.Electric current can be from electricity as a result,
Input terminal VIN is pressed to flow to output end via power switch M1, at this point, power switch M1 is used as the protective switch of direct mode operation.By
This, can be multiplexed the same device for power switching, to reduce chip area, reduce manufacturing cost.
Preferably, the feeder ear BS of promising mode selection circuit MODE power supply is arranged in integrated circuit, the integrated electricity in application
In the power inverter on road, capacitor C1 can be set between feeder ear BS and intermediate ends LX to maintain voltage between the two
Difference.
Meanwhile charge pump CP is connect with voltage input end VIN, it while it is working, can be by the voltage liter of voltage input end
It is exported after pressure.Mode selection circuit MODE selection signal SEL be the second state make the control terminal voltage of power switch M1 with
The output of charge pump CP changes, so that power switch M1 is switched to pass-through state.
Specifically, as shown in Fig. 2, mode selection circuit MODE includes selection circuit B1, switch S1, S2 and current source
I1, I2 and I3.Wherein, selection circuit B1 is according to the voltage of input voltage selection mode selection circuit feeder ear BS or intermediate ends LX
Output.The output end of selection circuit B1 is connect with the enable end of three state buffer T1.Switch S1 is connected to the defeated of the charge pump
Between outlet and the control terminal of power switch M1, be connected when selection signal is the second state, under the second mode, make
The output for obtaining charge pump can be applied to the control terminal of power switch M1.The connection of the input terminal of switch S2 and selection circuit, passes through
The input voltage that the switching of state adjusts selection circuit switches between high level and low level, so that selection circuit exports
The voltage of feeder ear BS or the voltage of intermediate ends LX.Switch S2 is connected when selection signal SEL is first state.Specifically, it opens
Close the adjusting of the input voltage of S2 and current source I2 and I3 cooperation progress selection circuit.As shown in Fig. 2, current source I2 is connected to
Between the output end of charge pump and the input terminal N1 of selection circuit.Switch S2 and current source I3 are connected in series in the defeated of selection circuit
Enter to hold between N1 and ground terminal.Current source I3 is connected between switch S2 and ground terminal.As a result, when switch S2 is connected, node
The voltage of N1 is pulled down to the voltage close to intermediate ends LX, and in switch S2 shutdown, the voltage of node N1 is pulled high to charge pump
Output voltage.Meanwhile current source I2 and current source I3 can provide electric current supply for the work of selection circuit.
When selection signal SEL is in first state, ON-OFF control circuit SLC is in running order, and switch S1 shutdown is opened
Close S2 conducting.To which the voltage of node N1 is pulled low, the voltage of selection circuit B1 selection output intermediate ends LX, this is one lower
Voltage, can control so that three state buffer T1 is in running order.Simultaneous Switching S1 shutdown, so that charge pump CP output end pair
Influence is not constituted in the control terminal of power switch M1.Power switch M1 is according to the control work of ON-OFF control circuit SLC as a result,
So that entire circuit is worked in a manner of switch converters.
When selection signal SEL is in the second state, charge pump CP is in running order, and switch S1 conducting, switch S2 is closed
It is disconnected.To which the voltage of node N1 is raised, selection circuit B1 exports the voltage of feeder ear BS, which makes three state buffer T1
In off state.Meanwhile switch S1 is connected so that the voltage Vpump=Vin+Vcc of charge pump CP output passes through current source I1
It is applied to power switch M1 control terminal.It, therefore, must since under pass-through state, the drive control of power switch M1 needs electric current
Current source I1 can be set when wanting, necessary driving current is provided.
Preferably, mode selection circuit MODE can also include switch S3 and current source I4, and the two is connected on charge pump CP
Output end and selection circuit B1 feeder ear BS between.Wherein, current source I4 is connect with the output end of charge pump CP, switch S3
It is connected between current source I4 and the feeder ear BS of selection circuit B1.Meanwhile switch S3 is by the output signal control of selection circuit B1
System.As a result, when selection signal SEL is in the second state, selection circuit B1 exports the voltage of higher feeder ear BS, this makes
Switch S3 conducting, current source I4 can provide driving voltage for selection circuit B1 as a result, export to meet selection circuit B1
Higher electric current exports demand when for high level.Meanwhile the voltage of feeder ear BS can be kept.The is in selection signal SEL
When one state, selection circuit B1 is smaller for the demand of electric current, and therefore, switch S3 is turned off, and does not provide additional electric current, and
Charge pump outputs voltage change can also be eliminated may the adverse effect caused by feeder ear BS.
It will be understood by those skilled in the art that for above using charge pump as the driving of power switch under direct mode operation into
Row explanation, but others are readily applicable to the present embodiment for the driving method of power switch.Meanwhile it being needed in driving current
When asking smaller, the current source in mode selection circuit can be omitted.Meanwhile mode selection circuit can be using similar other
Circuit structure realizes identical function.
