MB3800PFV中文资料富士通数据手册PDF规格书

■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.
