Diodes Incorporated AP5101 | Demoboard AP5101WG-EVM
1.5A, Step-Down Converter with 1.4Mhz Switching Frequency
Overview
| Topology | Buck Converter |
| Input voltage | 4.75-22 V |
| Output 1 | 3.3 V / 1.5 A |
Description
The AP5101WG-EVM is and evaluation boardfor the current mode step-down converter witha built-in power MOSFET .The AP5101 enables a constant output currentof up to 1.5A over a wide input supply rangefrom 4.75V to 24V. It provides excellent lineregulation, load regulation and transientresponse over the operating input voltage andtemperature range.The AP5101 is self protected, through a cycleby-cycle current limiting algorithm and an onchip thermal protection. The AP5101 isavailable in SOP-8L package.
Typical applications
- Battery Charger
- WLED Drivers
- Distributed Power Systems
- Pre-Regulator for Linear Regulators
