HIP6006

Buck and Synchronous-Rectifier Pulse-Width Modulator (PWM) Controller

DATASHEET

The HIP6006 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 HIP6006 integrates all of the control, output

adjustment, monitoring and protection functions into a single

package.

The output voltage of the converter can be precisely

regulated to as low as 1.27V, with a maximum tolerance of

1% over temperature and line voltage variations.

The HIP6006 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 HIP6006 protects against over-current conditions by

inhibiting PWM operation. The HIP6006 monitors the current

the need for a current sensing resistor.

NOTE: Intersil Pb-free 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.
