Introduction

AI Translation

ACT4070B is a wide input voltage step-down DC/DC converter that provides up to 3A output current at 300kHz switching frequency. ACT4070B is a replacement part for ACT4070 with advanced features such as lower standby current and higher light load efficiency. ACT4070B can be dropped into ACT4070 socket with only feedback resistance value changed. ACT4070B’s protection features include Cycle-byCycle current limit, thermal shutdown, and frequency foldback at over current and short circuit. The devices are available in a SOP-8EP package and require very few external devices for operation.
