Anachip AP1501 Buck Converter Datasheet
The AP1501 series is a monolithic step‑down DC/DC converter that integrates a switching transistor, providing up to 3 A load current without external driver components. It operates at a fixed 150 kHz switching frequency and includes thermal‑shutdown and current‑limit protection, as well as an ON/OFF shutdown control input.
The device is offered in two 5‑lead packages (TO‑220‑5L and TO‑263‑5L) and supports fixed output voltages of 3.3 V, 5 V, 12 V, or an adjustable version ranging from 1.23 V to 37 V. Typical efficiencies reach up to 90 % depending on the voltage version and load.
