Description

The Bay Linear B34063A series  is monolithic control circuit containing the primary functions required for DC-to-DC  converters. These devices consist of an internal temperature compensated reference, comparator, controlled, duty cycle oscillator with an active current limit circuit, driver and high current output switch. 
 
This B34063A series was specially designed to be incorporated in Step-Down and Step-Up and voltage-inverting applications with a minimum number of external component.
 
The B34063A is offer in 8-pin DIP or Surface mount package.
