Overview

BL8521 5.
5V, 1.
4MHz, 3A Synchronous Buck Converter DESCRIPTION The BL8521 is a synchronous, 1.
4MHz, fix frequency PWM Buck converter.
It is ideal for powering portable equipment that powered by a single cell Lithium-ion batter, or USB port.
The BL8521 can provide up to 3A of load current with output voltage as low as 0.
8V.
It can operate at 100% duty cycle for low dropout application.
With its peak current mode control and outside compensation, the BL8521 is stable with ceramic capacitors and small inductors.
BL8521 comprises a cycle-by-cycle current limit and thermal shutdown to protect itself from fault application.
BL8521 is available in DFN 3x3 -10 package.
FEATURES  Adjustable Outpu...
