AP3402
1.
0MHZ, 2A STEP-DOWN DC-DC BUCK CONVERTER
Description
The AP3402 is a 2A 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.
The AP3402 supports a range of input
voltages from 2.
7V 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 AP3402 employs internal power switch and synchronous rectifier to minimize external part count and realize high efficiency.
During shutdown, the input is disconnected from the output and the ...
