AP1509 Application Information and Demo Board User Guide
Overview
| Topology | Buck Converter |
| Input voltage | 12 V |
| Output 1 | 5 V / 2 A |
| Output 2 | 3.3 V / 2 A |
| Output 3 | 12 V / 2 A |
| IC revision | A |
Description
The AP1509 are a fully integrated step-down DC/DC converter, with the ability to drive 2Aload without the need of additional driver components. The AP1509 operates at a switchingfrequency of 150KHZ enabling the use of small size filter components. As a result, boardspace is reduced and BOM costs are lowered.
