HIP6004A PWM Controller and Output Voltage Monitor

DATASHEET HIP6004A Buck and Synchronous-Rectifier (PWM) Controller and Output Voltage Monitor FN4417 Rev.2.00 November 2002 The HIP6004A provides complete control and protection for a DC-DC converter optimized for high-performance microprocessor applications. It is designed to drive two N-Channel MOSFETs in a synchronous-rectified buck topology. The HIP60.

Features

a 15MHz gain-bandwidth product and 6V/ms slew rate which enables high converter bandwidth for fast transient performance. The resulting PWM duty ratio ranges from 0% to 100%. The HIP6004A 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 HIP6004A 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 HIP6004A monitors the current by using the rDS(ON) of the upper MOS.
