Overview
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.
