Diodes Incorporated AP62301 | Demoboard AP62301Z6-EVM
18V, 3A, Low Iq, COT Synchronous DC/DC Buck Converter
Overview
| Topology | Buck Converter |
| Input voltage | 4.2-18 V |
| Output 1 | 7 V / 3 A |
| IC revision | 1-1 |
Description
The AP62300/AP62301 is a 3A, synchronous buck converter with a wide input voltage range of 4.2V to 18V. The device fully integrates a 75mΩ high-side power MOSFET and a 45mΩ low-side power MOSFET to prov300TZ6ide high-efficiency step-down DC-DC conversion.The AP62300/AP62301 device is easily used by minimizing the external component count due to its adoption of Constant On-Time (COT) control to achieve fast transient response, easy loop stabilization, and low output voltage ripple.
Features
- VIN Range: 4.2V -18V
- Output Voltage range: 0.8V to 7V
- 3A Continuous Output Current
