OVERVIEW
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.
FEATURES
• 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).
• 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.
• Dead time period is adjustable over the whole range of duty ratio.
• Synchronization operation is possible.
APPLICATIONS
• LCD Displays
• PDAs
• Digital Still Cameras
• Hand-held and portable instruments
