mWSaver™ PWM Controller for Low Standby Power Battery-Charger Applications

Obsolete as of 25-Nov-2012

    This highly integrated PWM controller, FAN302HL, provides several features to enhance the performance of general flyback converters. The constant-current control, proprietary topology enables simplified circuit designs without secondary feedback circuitry for battery-charger applications.

    A proprietary Burst-Mode function with low operation current minimizes standby power consumption.

    The FAN302HL controller also provides several protections. Cycle-by-cycle current limiting ensures the fixed peak current limit level, even if a short circuit occurs. The gate output is clamped at 15V to protect the power MOS from high gate-source voltage conditions. If either VS OVP or internal OTP is triggered, the circuit enters Latch Mode until AC power is removed.

    Using FAN302HL, a charger can be implemented with few external components and minimized cost, compared to a conventional design or a linear transformer.
