Overview
AP3428/A 1.
5MHZ, 1A STEP-DOWN DC-DC BUCK CONVERTER Description The AP3428/A is a 1A step-down DC-DC converter.
At heavy load, the constant-frequency PWM control performs excellent stability and transient response.
No external compensation components are required.
Pin Assignments (Top View) The AP3428/A supports a range of input voltages from 2.
5V to 5.
5V, allowing the use of a single Li+/Li-polymer cell, multiple Alkaline/NiMH cell, and other standard power sources.
The output voltage is adjustable from 0.
6V to the input voltage.
The AP3428/A employs internal power switch and synchronous rectifier to minimize external part count and realize high efficiency.
During shutdown, the input is d...
