■ GENERAL DESCRIPTIONBL8512A BL8512A

The BL8512A is a monolithic step-down DC to

DC converter. The BL8512A works from a

4.75V to 20V input voltage range, and offers

up to 2A of continuous output current in a

compact SOIC 8 package.

The BL8512A operates in voltage mode.

Lower quiescent current and wider operating

input-voltage range are implemented by

Belling’s high-voltage BiCMOS-based

technology. Alternative PWM/PFM control

technique significantly improves the efficiency

for both light load and heavy load.

The BL8512A also integrates soft-start, over

load protection and under voltage lockout

protection etc., which minimized external

components and converter size.
