HIP6008 - Buck Pulse-Width Modulator (PWM) Controller and Output Voltage Monitor

General Description

COMP and FB are the available external pins of the error amplifier.

Key Features

  • a 15MHz gain-bandwidth product and 6V/µs slew rate which enables high converter bandwidth for fast transient performance. The resulting PWM duty ratio ranges from 0% to 100%. The HIP6008 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 HIP6008 protects against over-current conditions by inhibiting PWM operation. Built-in over-voltage protection triggers an external SCR to crowbar the input supply. T.

HIP6008 Data Sheet March 2000 File Number 4281.2 Buck Pulse-Width Modulator (PWM) Controller and Output Voltage Monitor The HIP6008 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 HIP6008 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 HIP6008 includes a 4-Input Digitalto-Analog Converter (DAC) that adjusts the output voltage from 2.0VDC to 3.5VDC in 0.1V increments. The precision reference and voltage-mode regulator hold the selected output voltage to within ±1.
