■ 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.
