The CP3800 is a single-channel switching regulator control IC for low voltage applications incorporating a soft start function and short circuit detection function. The device has a low minimum operating voltage of 1.8 V and is ideal for the power supply of battery-operated electronic equipment.
The CP3800 can be operated on two types: noninsulated input/output choppers (step-up, stepdown, and insulated input/output converters (flyback). The former type is used for DC/DC
converters and the latter type is used for DC/DC
converts and line-operation-type power supplies.
