FEATURES

The AA18375AP is a two-channel PWM DC-DC converter control IC that features low-voltage operation.

This IC can obtain the step-up, step-down and inverting voltages with a small number of external

components. Because the IC is compactly packaged, it is best suited for use as a power supply in

portable equipment.

• Wide supply voltage range: 3.6 V to 15 V

• Low current consumption: 1.3 mA typical

• Control in a wide output frequency range is possible (1 kHz to 500 kHz).

•

• Dead time

• Synchronization operation is possible.

• LCD Displays

• PDAs

• Digital Still Cameras

• Hand-held and portable instruments

Timer latch, short-circuit protection circuit is built in.

Circuit to prevent malfunction during low input voltage is built in.

Built-in reference voltage (1.28V) output pin.
