AP3441L - 3A STEP-DOWN DC-DC BUCK CONVERTER

Download the AP3441L datasheet PDF. This datasheet also covers the AP3441 variant, as both devices belong to the same 3a step-down dc-dc buck converter family and are provided as variant models within a single manufacturer datasheet.

General Description

The AP3441 and AP3441L are 3A step-down DC-DC converters.

At heavy load, the constant-frequency PWM control performs excellent stability and transient response.

No external compensation components are required.

Key Features

  • include over-temperature and short circuit protection, and under-voltage lockout to prevent deep battery discharge. The AP3441/L delivers 3A maximum output current while consuming only 55μA of no-load quiescent current. Ultra-low RDS(ON) integrated MOSFETs and 100% duty cycle operation make the AP3441/L an ideal choice for high output voltage, high current.

Description The AP3441 and AP3441L are 3A step-down DC-DC converters. At heavy load, the constant-frequency PWM control performs excellent stability and transient response. No external compensation components are required. AP3441/L 1MHZ, 3A STEP-DOWN DC-DC BUCK CONVERTER Pin Assignments (Top View) Pin 1 Mark The AP3441/L 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 AP3441/L 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.
