This reference design is a universal input, 430W constant current (CC), constant voltage (CV) charger for power tool applications. The reference design supports output voltage ranges of 0V to 12.5V in trickle-charge mode and 7.5V to 22.5V in fullcharge mode. The power factor correction (PFC) is disabled and the inductor-inductor capacitor (LLC) is placed into a low power mode when in tricklecharge mode, achieving a no-load standby power of 174mW at 115Vac and 325mW at 230Vac. This reference design uses the UCC28180, UCC256604, UCC24612, TL331 and TPS7B8133 devices.
