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 B3800 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.
