Description
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. A
typical output CV/CC characteristic is shown in Figure 1.
