AIC1568  
4-bit DAC, Simple PWM Power Regulator  
FEATURE  
DESCRIPTION  
Compatible with HIP6008.  
Simple Voltage-Mode PWM Control.  
Fast Transient Response.  
The AIC1568 is a high power, high efficiency  
switching regulator controller optimized for high  
performance microprocessor applications. It is  
1.5% 4-Bit Digital-to-Analog Output Voltage.  
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.  
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.  
APPLICATIONS  
Power Supply for Pentium, Pentium Pro, Power  
PCand AlphaMicroprocessors.  
High-Power 5V to 3.xV DC/DC Regulators.  
Low-Voltage Distributed Power Supplies.  
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%.  
The error amplifier 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.
