PRELIMINARY

Switching Regulator Controller

■OVERVIEW

The AA18380 is a single-channel PWM DC-DC regulator control IC that supports low-voltage operation. This

IC features a low minimum operating voltage of 1.8 V and low current consumption, is optimal for use in

high-efficiency power supplies for portable electronic equipment.

■FEATURES

• Wide operating supply voltage range: 1.8 V to 15 V

• Stable reference voltage circuit: 1.25V.

• Low current consumption: Typically 5.5 mA in operation, 1 µA or less in stand-by

• Wide PWM output frequency range: 10 kHz to 1 MHz

• Incorporates a soft start circuit and adjustable soft start time.

• Timer latch short-circuit protection circuit (SCP).

• Low input voltage malfunction prevention circuit (U.V.L.O.)

• On/off control function

• Totem-pole type output by using an external resistor to set the output current (for NPN transistors)
