PMP10110.2, Universal 120 to 440 DC Input to 30Vmax @ 6A Lead-acid Battery Charger Reference Design with PFC

PMP10110.2, Universal 120 to 440 DC Input to 30Vmax@6A Lead-acid Battery Charger Reference Design with PFC. The PMP10110 design converts the universal input AC voltage to isolated 17V to 30V @ 6A and is suitable to charge lead-acid or Li-Ion batteries. The converter is a constant-V and constant-I generator and the set points for output voltage (charge level) and current are settable by means of two PWM signals. The first stage is a PFC boost while the isolation ad current stabilization is performed by DC-DC half bridge stage. An isolated quasi-resonant flyback converter supplies all internal voltages and provide some extra current for external loads (fan or analog section), in details 12V@400mA and 5V@300mA
