B3800
Description
The Bay Linear B3800 series is monolithic control circuit
containing the primary functions required for DC-to-DC
converters. This device is design for low voltage applications
incorporating a soft start function and sort circuit detection
function. The device has a low minimum operating voltage of
1.8V and is ideal for the power supply of battery-operated
electronic equipments.
This series was specially designed to be incorporated in Step-
Down and voltage-inverting applications with a minimum
number of external components.
The B3800 is offer in 8-pin DIP or Surface mount package.
