Features

High reliability by all required functions integrating

1. Continuous conduction mode suitable for the system with a large amount and frequency of a current change.

2. ON/OFF support of the main converter and the load by a PG signal and a hold function.

3. Hold function against an AC temporary blackout

4. Over-voltage protection with a feedback loop absence detecting function

5. Quick soft-start

6. Improvement of the load regulation by a Gm amplifier

Small and high reliability system

Example of Application Circuit

• The HA16174 stabilizes the over-current control of PFC unit and sets the S/S ineffective time by a hold function in time of an AC temporary blackout.

• The HA16163 makes up a full bridge and achieves small and high efficiency trances.
