AP61300/AP61302 2.4V TO 5.5V INPUT, 3A LOW IQ SYNCHRONOUS BUCK CONVERTER Description The DIODES AP61300/AP61302 is a 3A, synchronous buck converter with a wide input voltage range of 2.4V to 5.5V. The device fully integrates a 70mΩ high-side power MOSFET and a 50mΩ low-side power MOSFET to provide high-efficiency, step-down, DC-DC conversion. The AP61300/AP61302 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. Pin Assignments (Top View) FB 1 6 OUT FB 1 6 PG GND 2 AP61300 5 EN GND 2 AP61302 5 EN VIN 3 4 SW VIN 3 4 SW SOT563 Features  VIN: 2.4V to 5.
