AIC1568 Datasheet 4-bit Dac/ Simple Pwm Power Regulator

Manufacturer: Analog Intergrations Corporation

Overview: AIC1568 4-bit DAC, Simple PWM Power Regulator FEATURE Compatible with HIP6008. Simple Voltage-Mode PWM Control. Fast Transient Response. ±1.5% 4-Bit Digital-to-Analog Output Voltage. Adjustable Current Limit without External Sense Resistors. Full 0% to 100% Duty Ratio. 200KHz Free-Running Oscillator, Programmable up to 350KHz. Power-Good Output Voltage Monitor. Short Circuit Protection with Low Short Circuit Output Current. The internal 4-bit Digital-to-Analog Converter (DAC) adjusts the output voltage from 2.0V to 3.5V in 0.1V increments. The precision reference and voltage-mode control can provide output regulation within ±1.5% over temperature and line voltage shifts. The internal oscillator of the AIC1568 free-runs at 200KHz and can be adjusted up to 350KHz. The resulting PWM duty ratio ranges from 0% to 100%.

General Description

The AIC1568 is a high power, high efficiency switching regulator controller optimized for high performance microprocessor applications.

It is designed to drive an N-channel MOSFET in a standard buck topology.

Featuring a digitally programmable switching regulator, the AIC1568 includes monitoring and protection capabilities in addition to all the essential PWM control functions.

Key Features

  • a 11MHz bandwidth and 6V/µS slew rate, which enables high converter bandwidth for fast transient response. The AIC1568 provides adjustable over current and short circuit protections. It senses the output current across the on resistance of the N-channel MOSFET without an external low value sense resistor. It also monitors the output voltage with a window comparator and issues a power good signal when the output is within 10% of the rated output voltage.
