HA16141FP Overview
The HA16141P/FP and the HA16142P/FP are power supply controller ICs bining an AC-DC converter switching controllers for power factor correction and off-line power supply switching controllers. PFC (Power factor correction) section employs average current mode PWM and off-line power supply control section employs peak current mode PWM. The HA16142P/FP is the change version of HA16141P/FP’s PWM maximum on duty cycle.
