Overview: DATASHEET HIP6005
Buck Pulse-Width Modulator (PWM) Controller and Output Voltage Monitor FN4276 Rev.2.00 March 2000 The HIP6005 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 HIP6005 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 HIP6005 includes a 5-input digitalto-analog converter (DAC) that adjusts the output voltage from 2.1VDC to 3.5VDC in 0.1V increments and from 1.3VDC to 2.1VDC in 0.05V steps. The precision reference and voltage-mode regulator hold the selected output voltage to within 1% over temperature and line voltage variations.
The HIP6005 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.
