Regulator Controller for  
Pentium® III Processor

FEATURES  
DESCRIPTIO  
The LTC®1753 is a high power, high efficiency switching  
regulator controller optimized for 5V input to a digitally  
programmable 1.3V-3.5V output. The internal 5-bit DAC  
programs the output voltage from 1.3V to 2.05V in 50mV  
incrementsandfrom2.1Vto3.5Vin100mVincrements. The  
precision internal reference and an internal feedback system  
provide an output accuracy of ±1.5% at room temperature  
and typically ±2% over temperature, load current and line  
voltage shifts. The LTC1753 uses a synchronous switching  
architecture with two external N-channel output devices,  
providing high efficiency and eliminating the need for a high  
power,highcostP-channeldevice.Additionally,itsensesthe  
output current across the on-resistance of the upper N-  
channel FET, providing an adjustable current limit without an  
external low value sense resistor.

Phase Lead Compensation for Remote Sensing  
■
Overtemperature Protection  
■
Flags for Power Good and Overvoltage Fault  
■
19A Output Current Capability from a 5V Supply  
■
Dual N-Channel MOSFET Synchronous Driver  
■
Initial Output Accuracy: ±1.5%  
■
Excellent Output Accuracy: ±2% Typ Over Line,  
Load and Temperature Variations  
High Efficiency: Over 95% Possible  
■
■
Adjustable Current Limit Without External Sense  
Resistors  
■
Available in 2O-Lead SSOP and SW Packages  
The LTC1753 free-runs at 300kHz and can be synchronized  
to a faster external clock if desired. It provides a phase lead  
compensation scheme and under harsh loading conditions,  
the PWM duty cycle can be momentarily forced to 0% or  
100% to reduce the output voltage recovery time.
