UCC3588  
PRELIMINARY  
5-Bit Programmable Output BiCMOS Power Supply Controller  
FEATURES  
DESCRIPTION  
• 5-Bit Digital-to-Analog Converter  
(DAC) supports Intel Pentium II  
The UCC3588 synchronous step-down (Buck) regulator provides accurate  
high efficiency power conversion. Using few external components, the  
UCC1588 converts 5V to an adjustable output ranging from 3.5VDC to  
2.1VDC in 100mV steps and 2.05VDC to 1.3VDC in 50mV steps with 1%  
DC system accuracy. A high level of integration and novel design allow this  
16-pin controller to provide a complete control solution for today’s  
demanding microcontroller power requirements. Typical applications  
include on board or VRM based power conversion for Intel Pentium II  
microprocessors, as well as other processors from a variety of  
manufacturers. High efficiency is obtained through the use of synchronous  
rectification.  
• Microprocessor VID Codes  
• Compatible with 5V or 12V Systems  
• 1% Output Voltage Accuracy  
Guaranteed  
• Drives 2 N-Channel MOSFETs  
• Programmable Frequency to 800kHz  
• Power Good OV / UV / OVP Voltage  
Monitor  
The softstart function provides a controlled ramp up of the system output  
voltage. Overcurrent circuitry detects a hard (or soft) short on the system  
output voltage and invokes a timed softstart/shutdown cycle to reduce the  
PWM controller on time to 5%.  
• Undervoltage Lockout and Softstart  
Functions  
• Short Circuit Protection  
• Low Impedance MOSFET Drivers  
• Chip Disable  
The oscillator frequency is externally programmed with RT and operates  
over a range of 50kHz to 800kHz. The gate drivers are low impedance to-  
tem pole output stages capable of driving large external MOSFETs. Cross  
conduction is eliminated by fixed delay times between turn off and turn on  
of the external high side and synchronous MOSFETs. The chip includes  
undervoltage lockout circuitry which assures the correct logic states at the  
outputs during power up and power down.
