AP3429 - 2A STEP-DOWN DC-DC BUCK CONVERTER

Datasheet Summary

Description

The AP3429/A 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.

Features

include over-temperature and short circuit protection, and under-voltage lockout to prevent deep battery discharge. The AP3429/A 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 AP3429/A an ideal choice for high output voltage, high current.

NOT RECOMMENDED FOR NEW DESIGN NO ALTERNATE PART AP3429/A 1.0MHZ, 2A STEP-DOWN DC-DC BUCK CONVERTER Description The AP3429/A 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 AP3429/A 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 AP3429/A 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.
