4. Circuit Description

1. Power supply (DC/DC Converter)
The AP1501 is monolithic IC designed for M/B DC/DC converter, and owns the ability of driving a 3A load without
any additional transistor component.
The AP1501 operates at a switching frequency of 150KHz and thus allows smaller-sized filter components than what
would be needed with lower frequency switch regulator.
