AP61100/AP61102
2.3V TO 5.5V INPUT, 1A LOW IQ SYNCHRONOUS BUCK CONVERTER Description Pin Assignments 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. (Top View) FB 1 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. GND 2 6 OUT AP61100 VIN 3 Features Applications VIN: 2.3V to 5.5V
