Diodes Incorporated AP61100 | Demoboard AP61100Z6-EVM
2.3V To 5.5V Input, 1A Low IQ Synchronous Buck Converter
Overview
| Topology | Buck Converter |
| Input voltage | 2.3-5.5 V |
| Output 1 | 3.6 V / 1 A |
| IC revision | 3-2 |
Description
The AP61100/AP61102 is a 1A, synchronous buck converter with a wide input voltage range of 2.3V to 5.5V. The device fully integrates a 110mΩ high-side power MOSFET and an 80mΩ low-side power MOSFET to provide high-efficiency step-down DC-DC conversion. The AP61100/AP61102 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.The device is available in a SOT563 package.
