■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.
