PJ3800CA中文资料ETC数据手册PDF规格书

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

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.
