PJ3800
Low Voltage Switching Regulator Controller
1-8
2003/04.rev.A
he 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.
.
Wide supply voltage operating range: 1.8 to 15 V
Low current consumption: Typically 5.5 mA in
operation, 1 mA 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.
