DATASHEET HIP6005B Buck Pulse-Width Modulator (PWM) Controller and Output Voltage Monitor FN4568 Rev 2.00 February 1999 The HIP6005B provides complete 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-compatible 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. The error amplifier features a 15MHz gain-bandwidth product and 6V/s slew rate which enables high converter bandwidth for fast transient performance. The resulting PWM duty ratio ranges from 0% to 100%. The HIP6005B monitors the output voltage with a window comparator that tracks the DAC output and issues a Power Good signal when the output is within 10%. The HIP6005B protects against over-current and over-voltage conditions by inhibiting PWM operation. Additional built-in over-voltage protection triggers an external SCR to crowbar the input supply. The HIP6005B monitors the current by using the rDS(ON) of the upper MOSFET which eliminates the need for a current sensing resistor. Ordering Information TEMP. PART NUMBER RANGE (oC) PACKAGE PKG. NO.
