Diodes Incorporated AP61102 | Demoboard AP61102Z6-EVM

Description

The AP61102 is a 1A, synchronous buck converter with an input voltage range of 2.3V to 5.5V and fully integrates a 120mΩ high-side power MOSFET and a 80mΩ low-side power MOSFET to provide high-efficiency step-down DC/DC conversion. The 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 responses, ease loop stabilization, and low output voltage ripple.
