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 or SOL-8, SSOP-8)
