HIP6004E

Buck and Synchronous-Rectifier (PWM) Controller and Output Voltage Monitor

DATASHEET

The HIP6004E 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 HIP6004E 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 HIP6004E includes a 5-input digital-

to-analog converter (DAC) that adjusts the output voltage

precision reference and voltage-mode regulator hold the

selected output voltage to within

1% over temperature and

line voltage variations.

The HIP6004E provides simple, single feedback loop,

voltage-mode 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 HIP6004E 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 HIP6004E

protects against over-current and overvoltage conditions by

inhibiting PWM operation. Additional built-in overvoltage

protection triggers an external SCR to crowbar the input

supply. The HIP6004E monitors the current by using the

a current sensing resistor.
