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
(Top View)
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.
FB 1 6 OUT FB 1 6 PG
The AP61100/AP61102 device is easily used by minimizing the
GND 2 AP61100 5 EN GND 2 AP61102 5 EN
external component count due to its adoption of Constant On-Time (COT) control to achieve fast transient response, easy loop
VIN 3 4 SW VIN 3 4 SW
stabilization, and low output voltage ripple. The device is available in a SOT563 package.
