Diodes Incorporated AP61100Z6 | Demoboard AP61100Z6-EVM

Description

The AP61100 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 AP61100 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. Moreover,AP61100 also features force PWM mode control through EN pin.The device is available in a SOT563 package.
