DESCRIPTION

· The AN8018SA is a two-channel PWM DC-DC converter control IC designed for low-voltage operation, capable of step-up, step-down, and inverting voltages with minimal external components.

· It operates from a minimum voltage of 1.8 V, suitable for use with two dry batteries, and comes in a 16-pin surface mount package with a 0.65 mm pitch, ideal for compact, efficient portable power supplies.

FEATURES

· Wide operating voltage range from 1.8 V to 14 V.

· High precision reference voltage circuit with ±2% allowance.

· Output frequency control range from 20 kHz to 1 MHz.

· Built-in wideband error amplifier with a single gain bandwidth of 10 MHz.

· Timer latch short-circuit protection with a typical charge current of 1.1 µA.

· Under-voltage lock-out circuit with a typical operation-starting voltage of 1.67 V.

· Variable dead-time and staggered turn-on timing for flat switching current.

· On/off control function with a maximum standby mode current of 5 µA.

· Capable of parallel operation.

· Totem pole output with a maximum source-current of -50 mA and sink-current of +80 mA.

APPLICATIONS

· Suitable for LCD displays, digital still cameras, and PDAs.
