ACT30

Datasheet Rev 2, 5/2005 ACT30 ACT30 FEATURES HIGH PERFORMANCE OFF-LINE CONTROLLER ActiveSwitcherTM IC Family GENERAL DESCRIPTION The ACT30 is a high performance green-energy offline 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 SOT23-5), resulting in lowest total cost solution. The ACT30 design has 6 internal terminals and is a pulse frequency and width modulation IC with many flexible packaging options. One combination of internal terminals is packaged in the space-saving TO-92 package (A/B/C/D versions) for 65kHz or 100kHz switching frequency and with 400mA or 800mA current limit. The E version (SOT23-5) can be configured for higher current limit. Consuming only 0.15W in standby, the IC features over-current, hiccup mode short circuit, and under-voltage protection mechanisms. The ACT30 is ideal for use in high performance universal adaptors and chargers. For highest performance versus cost and smallest PCB area, use the ACT30 in combination with the ACT32 CV/CC Controller.
