AP61100 Datasheet 1a Low Iq Synchronous Buck Converter

Manufacturer: Diodes Incorporated

Overview: AP61100/AP61102 2.3V TO 5.5V INPUT, 1A LOW IQ SYNCHRONOUS BUCK.

General Description

The DIODESTM 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 lowside 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.
