The MB3800 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.

Features

■ Wide supply voltage operating range: 1.8 V to 15 V

■ Low current consumption: Typically 5.5 mA in operation, 1 A 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.

■ Two types of packages (SOP-8 : 2 types)

Application

■ LCD monitor/panel

■ Power supply module

■ Portable apparatus etc.
