DESCRIPTION
The UCC3830-4/-5/-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
Intel鈥檚 4-bit Pentium廬 Pro and 5-bit Pentium廬 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.
