PJ3800
Low Voltage Switching Regulator Controller
The PJ3800 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
z Wide supply voltage operating range: 1.8 to 15 V
z Low current consumption: Typically 5.5 mA in
operation, 1 mA or less in stand-by
z High speed operation is possible: Maximum 1 MHz
z The error amplifier gain is set inside the IC, so
peripheral components are minimized.
z Incorporates a soft start circuit.
z Incorporates a timer-latch type short circuit detection
circuit (SCP).
z Totem-pole type output with adjustable on/off current
(for NPN transistors)
z Incorporates a stand-by function.
