1.5Amp DC-to-DC Converter Control Circuit
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 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.
