AP3419 - Diodes

AP3419 2A STEP-DOWN DC-DC BUCK CONVERTER

The AP3419 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 Assignments (Top View) Pin 1 Mark The AP3419 supports a range of input voltages from 2.7V to 5.5V, allowing the use of a single Li+/Li- polymer cell, multi.

Features

include over-temperature and short circuit protection, and under-voltage lockout to prevent deep battery discharge. The AP3419 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 AP3419 an ideal choice for high output voltage, high current applications which require a low dropout threshold. The AP3419 is available in TSOT26 package. EN 1 6 FB GND 2 5 NC LX 3 4 VIN TSOT26 Applications
