AP61102中文资料2.3V TO 5.5V INPUT, 1A LOW IQ SYNCHRONOUS BUCK CONVERTER数据手册Diodes规格书

描述 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.
