Qorvo's ACT4070B is a wide input voltage step-down DC/DC converter that provides up to 3 A output current at 300 kHz 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 the feedback resistance value changed.
ACT4070B's protection features include cycle-by-cycle current limit, thermal shutdown and frequency foldback at over-current and short circuit. The device is available in a SOP-8EP package and requires very few external devices for operation.
