VIN+----- input power anodes.
VIN------ input power cathode.
VOUT+----- out-put supply anodes.
VOUT----- out-put supply cathode.
The anode of VREF+----- reference power sources
C1 is input filter capacitor.
C2 is output filter capacitor.
C3 is current sample feedback filtering.
R1, R2, R5, C3 form current sample feedback line.
R3, R4 are voltage sample feedback circuit.
D1 is isolation diode.
Operation principle explanation:
Using stable reference power supply as reference voltage, using R1, R2, R5 divide to obtain the voltage equal with FB, so as to
By FB the inside PWM of adjustment DCDC IC is gone to control the size of output current.For example, when output current becomes larger, in sampling electricity
Voltage on resistance R5 will raise, and since VRFE+ is fixed value, so as to be that FB voltages become larger, FB becomes larger, and duty cycle will subtract
It is few, so as to be that output current is reduced, and a complete feedback is completed, achieve the purpose that stabling current exports.
Constant current calculates:
If the voltage that R5 upstream overcurrent generates is VIo, output current Io
Reference voltage is VREF+=2.5V,
FB voltages are VFB=0.6V,
R5=0.1 Ω, R1=40K Ω, R2=10K Ω
Then:
VIo=Io*R5
VFB=VIo+ ((VREF+-VIo) * R2/ (R1+R2))
It calculates:
Io=(VFB* (R1+R2)-R2*VREF+)/R1*R5
The equation if K=(VFB* (R1+R2)-R2*VREF+)/R1 is taken
Io=K/R5
In terms of calculation formula, Io output currents and output voltage and input voltage do not have any relation, only and VFB.R1,
R2, VREF are related, and these parameters are in specific design, they be all it is fixed (VFB be in stable state it is fixed, for
Chip fp7192 constant pressure chips, steady-state value 0.6v), so K is necessarily a fixed value, so formula:
Io=K/R5 has the fabulous linearity and with excellent controllability.
The occurrence that parameter imparting above is set above can be obtained:
Io=(VFB* (R1+R2)-R2*VREF+)/R1*R5
=(0.6* (40+10) -10*2.5)/40*0.1
=1.25A
Constant pressure chip.About 0.8 yuan of cost
It can be seen that, this scheme introduces fixed VREF+ from above equation, is only taken so that Io becomes one with R5
The linear equation of sample resistance, makes Io become constant, so as to achieve the purpose that constant current.
The characteristics of this programme reference voltage constant flow method, is as follows:
1. fix VREF+ voltages, control and stability control convenient for precision using stablizing.
It is fed back 2. current sample is become electric resistance partial pressure by use, it is more simple and reliable.
3. applicability is wide, the circuit of any required constant current can use.
4. cost is greatly reduced, such as does 12V/1A outputs using IC constant current schemes and wants 3 yuan or more, and is existed using this programme
Within 1 yuan.
The constant pressure driving chip uses ZTP7192 devices.Can also be other constant pressure driving chips in the market.Such as
MP1495,MP1593,RT8296,MC34063,FP5138…………。
To prevent measuring device from tilting, necessary supporting mechanism (such as stent) can be set.Photovoltaic module can be installed
On the ground, prevent that measuring device is overweight.
