Overview: DATASHEET HIP6005B
Buck Pulse-Width Modulator (PWM) Controller and Output Voltage Monitor FN4568 Rev 2.00 February 1999 The HIP6005B provides plete control and protection for a DC-DC converter optimized for high-performance microprocessor applications. It is designed to drive an N-Channel MOSFET in a standard buck topology. The HIP6005B integrates all of the control, output adjustment, monitoring and protection functions into a single package.
The output voltage of the converter is easily adjusted and precisely regulated. The HIP6005B includes a fully TTL-patible 5-input digital-to-analog converter (DAC) that adjusts the output voltage from 1.3VDC to 2.05VDC in 0.05V increments and from 2.1VDC to 3.5VDC in 0.1V steps. The precision reference and voltage-mode regulator hold the selected output voltage to within 1% over temperature and line voltage variations.
The HIP6005B provides simple, single feedback loop, voltagemode control with fast transient response. It includes a 200kHz free-running triangle-wave oscillator that is adjustable from below 50kHz to over 1MHz.
