Active- Semi ACT30 Rev 5, 05-Jun-09 High Performance Off-Line Controller TM ActiveSwitcher IC Family FEATURES GENERAL DESCRIPTION Lowest Total Cost Solution The ACT30 is a high performance green-energy off- line power supply controller. It features a scalable 0.15W Standby Power driver for driving external NPN or MOSFET Emitter Drive Allows Safe NPN Transistor transistors for line voltage switching. This Flyback Use proprietary architecture enables many advanced features to be integrated into a small package Hiccup Mode Short Circuit (TO-92 or SOT23-B), resulting in lowest total cost solution. Current Mode Operation The ACT30 design has six internal terminals and is Over-Current Protection a pulse frequency and width modulation IC with Under-voltage Protection with Auto-Restart many flexible packaging options. One combination of internal terminals is packaged in the space- Proprietary Scalable Output Driver saving TO-92 package (A/B versions) for 65kHz or Flexible Packaging Options (Including TO-92) 100kHz switching frequency and with 400mA or 800mA current limit. 65kHz or 100kHz Switching Frequency Consuming only 0.15W in standby, the IC features Selectable 0.4A to 1.2A Current Limit over-current, hiccup mode short circuit, and under- voltage protection mechanisms. APPLICATIONS The ACT30 is ideal for use in high performance Battery Chargers universal adaptors and chargers. For highest performance versus cost and smallest PCB area, Power Adaptors use the ACT30 in combination with the ACT32 Standby Power Supplies CV/CC Controller.
