The UCC3830-4/-5/-6 is a fully integrated single chip solution ideal for powering 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's 4-bit Pentium Pro and 5-bit Pentium II VID codes.
