HIP6007

Buck Pulse-Width Modulator (PWM) Controller

DATASHEET

The HIP6007 provides complete control and protection for

a DC-DC converter optimized for high-performance

microprocessor applications. It is designed to drive an

N-Channel MOSFET in a standard buck topology. The

HIP6007 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 HIP6007 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 HIP6007 protects against over-current conditions by

inhibiting PWM operation. The HIP6007 monitors the current

the need for a current sensing resistor.
