HIP6005B PWM Controller and Output Voltage Monitor

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 .

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 MOS.
