Overview
FUJITSU SEMICONDUCTOR DATA SHEET DS04-27212-2E ASSP For Power Supply Applications BIPOLAR Switching Regulator Controller (Low Voltage) MB3800 s DESCRIPTION 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.
s FEATURES • • • • • • • • • Wide supply voltage operating range: 1.
8 to 15 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.
Three types of packages (SOP-8 o...
