MB3800
Switching Regulator Controller
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.
