5-Bit Microprocessor Power Supply Controller

The UCC3830-4 UCC3830-5 UCC3830-6 is a fully integrated single chip solution ideal for power- ing high performance Microprocessors The chip includes an average current mode PWM Controller has a fully integrated 5-Bit DAC and includes an on-board precision reference and voltage monitor circuitry. The UCC3830-x converts 5VDC to an adjustable output, ranging from 3.5VDC down to 1.8VDC with 1% DC system accuracy (see Table 1). The UCC3830-x fully supports Intels 4-bit Pentium Pro and 5-bit Pentium II VID codes. The accuracy of the DAC reference combination is 1%. The overvoltage and undervoltage Comparators monitor the system output voltage and indicate when it rises above or falls below its programmed value by more than 8.5%. A second overvoltage protection Comparator pulls the current Amplifier output voltage low to force zero duty cycle when the system output voltage exceeds its designed value by more than 17.5%. This Comparator also terminates the cycle. Undervoltage lockout circuitry assures the correct Logic states at the outputs during powerup and powerdown. The Gate output CAN be disabled by bringing the CAO/ENBL pin to below 0.8V. By Texas Instruments
