Diodes Incorporated AP61300Q | Demoboard Z6-EVM

Description

The AP61300Q is a 3A, 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 AP61300Q 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, AP61300Q also features force PWM mode control through EN pin.
