Buck and Synchronous-Rectifier (PWM)

Controller and Output Voltage Monitor

The HIP6004D 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 HIP6004D 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 HIP6004D includes a fully TTL-

compatible 5-input digital-to-analog converter (DAC) that

adjusts the output voltage from 1.1V

increments steps. The precision reference and voltage-

mode regulator hold the selected output voltage to within

±1% over temperature and line voltage variations.

The HIP6004D 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 HIP6004D 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 HIP6004D

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 HIP6004D monitors the current by using the

a current sensing resistor.

Ordering Information

Add “-T” suffix for tape and reel.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free material

sets; molding compounds/die attach materials and 100% matte tin plate

termination finish, which are RoHS compliant and compatible with both SnPb

and Pb-free soldering operations. Intersil Pb-free products are MSL classified

at Pb-free peak reflow temperatures that meet or exceed the Pb-free

requirements of IPC/JEDEC J STD-020.
