1 / 19 page Features • Wide supply voltage operating range: 1.8 to13 V • Low current consumption: Typically 5.5 mA in operation, 1 µA or less in stand-by • High speed operation is possible: Maximum 1 MHz • The error amplifier gain is set inside the IC, so peripheral components are minimized. • Incorporates a soft start circuit. • Incorporates a timer-latch type short circuit detection circuit (SCP). • Totem-pole type output with adjustable on/off current (for NPN transistors) • Incorporates a stand-by function. Applications • Power source for battery-powered equipment • Power source for cameras, camcorders, VCRs, PDAs, electronic data banks, and hand-held Communication equipment General Description 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: non- insulated input/output choppers (step-up, step- down , and insulated input/output converters (fly- back). 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.
