GENERAL DESCRIPTION
The ACT30 design has six 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 spacesaving TO-92 package (A/B versions) for 65kHz or 100kHz switching frequency and with 400mA or 800mA current limit. Consuming only 0.15W in standby, the IC features over-current, hiccup mode short circuit, and undervoltage protection mechanisms. The ACT30 is ideal for use in high performance universal adaptors and chargers.
