Switching Regulator Controller
(Low Voltage)
MB3800
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.
FEATURES
Wide supply voltage operating range: 1.8 V 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 : 2 types, SSOP-8 : 1 type)
Application
• LCD monitor/panel
• Power supply module
• Portable apparatus
etc.
