AP3402
1.0MHZ, 2A STEP-DOWN DC-DC BUCK CONVERTER
Description
Pin Assignments
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.

Pin 1 Mark
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 shutdown current is less
than 1μA. Other key features include over-temperature and short
circuit protection, and under-voltage lockout to prevent deep battery
discharge.

The AP3402 delivers 2A maximum output current while consuming
only 90μA of no-load quiescent current. Ultra-low RDS(ON) integrated
MOSFETs and 100% duty cycle operation make the AP3402 an ideal
choice for high output voltage, high current applications which require
a low dropout threshold.
The AP3402 is available in TSOT26 package.
