AP3401 - Diodes

AP3401 1A STEP-DOWN DC - DC BUCK CONVERTER

The AP3401 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) Pin 1 Mark The AP3401 supports a range of input voltages from 2.5V to 5.5V, allowing the use of a single Li+/Li-polymer cell, multip.

Features

include over-temperature and short circuit protection, and under-voltage lockout to prevent deep battery discharge. The AP3401 delivers 1A maximum output current while consuming only 40μA of no-load quiescent current. Ultra-low RDS(ON) integrated MOSFETs and 100% duty cycle operation make the AP3401 an ideal choice for high output voltage, high current applications which require a low dropout threshold. Pulse skip mode allows to maintain high efficiency at light-load conditions. The AP3401 is available in TSOT26, U-DFN2020-6 (Type J) packages. Features
