AP1501-K5G-U

Low Dropout LDO Regulators 3A DC-DC CONV 150kHz 400V ESD +45 Vcc

General Description

The AP1501 is a fully integrated step-down DC/DC converter, with the ability to drive 3A load without the need of additional driver components. The AP1501 operates at a switching frequency of 150KHZ enabling the use of small size filter components. As a result, board space is reduced and BOM costs are lowered.
