Overview
NOT RECOMMENDED FOR NEW DESIGN USE AP61300 AP3419 1.
0MHZ, 2A STEP-DOWN DC-DC BUCK CONVERTER Description 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, multiple Alkaline/NiMH cell, and other standard power sources.
The output voltage is adjustable from 0.
6V to the input voltage.
The AP3419 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 AP3419 delivers 2A maximum output current...
