DC voltage is exported after pressure, is powered to circuit, chip IC 1 is switching regulator, and IC2 is linear voltage regulator.As input voltage VCC
During ＞ setting value V, IC1 will be turned off, and provide output voltage by IC2 in the case.VCC is then by D1 and R1 with floating current pair
Battery E is charged.As VCC ＜ setting value V, IC2 is then off state, and VCC then boosts to 3.6v cell voltage
5V, load current is 50mA.IC2 carries low battery voltages monitor, and VCC is detected by R6, R7.Monitor is in 7 pin
Output driving phase inverter V1, V1 driving IC1 and IC2 6 pin and two, 5 pin shut-off input pins in turn again.The two inputs
Level with opposite polarity.IC1 and IC2, which shares feedback resistance R2 and R3, makes two voltage-stablizers to carry out output voltage U1
Monitoring.When IC2 is turned off, it, which is exported, is cut off.When IC1 is turned off, chip maintains low power state, therefore ought have input voltage
During VCC, linear voltage regulator IC2 provides 5V voltage output.When without input voltage VCC, the boosting constituted centered on IC1 is opened
Close the voltage output that cell voltage is then transformed to 5V by voltage-stablizer.Therefore, either with or without input voltage VCC, output voltage U1 is
Normal value will be kept.
