Circuit Design of 16W Wide Voltage Input Lead Acid Battery Charger
Summary:
The circuit can provide CV/CC output for charging lead-acid batteries, including fire/burglar alarms and emergency lights.
The design uses many of the features of the TOPSwitch-GX series. Line voltage undervoltage and overvoltage (100 V and 450 V each) are implemented with a single resistor (R13). Undervoltage detection eliminates output jitter on/off, and overvoltage provides protection against input voltage transients and long-term surges, eliminating the need for an input MOV. The TOP244PN in the DIP8 package does not require an external heatsink and can be cooled by the PCB.
