ACT30AHT

Switching Controllers Low Cost Charger Solution

GENERAL DESCRIPTION

The ACT30 is a high performance green-energy off line power supply controller. It features a scalable driver for driving external NPN or MOSFET transistors for line voltage switching. This proprietary architecture enables many advanced

features to be integrated into a small package TO-92 or SOT23-B, resulting in lowest total cost solution.
