特点:
- boundary conduction mode
- low power consumption
- vccuvlo
- resister detection for zcd
- switching loss reduction, noise reduction by zcd
- dynamic and static ovp by the vs pin
- high accuracy over current detection (±4 %)
- error amplifier input short protection
- stable mosfet gate drive by the clamper
- protection function by the ovp pin
- over voltage reduce by soft start
- safe design by the is-gnd short timer operation
