Buck and Synchronous-Rectifier (PWM)

Controller and Output Voltage Monitor

The HIP6004 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 HIP6004 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 HIP6004 includes a 5-input

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

voltage from 2.1V

1.3V

and voltage-mode regulator hold the selected output voltage

to within ±1% over temperature and line voltage variations.

The HIP6004 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/μs slew rate which enables high converter bandwidth for

fast transient performance. The resulting PWM duty ratio

ranges from 0% to 100%.

The HIP6004 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 HIP6004

protects against over-current conditions by inhibiting PWM

operation. Built-in over-voltage protection triggers an

external SCR to crowbar the input supply. The HIP6004

monitors the current by using the r

MOSFET which eliminates the need for a current sensing

resistor.
