Buck Pulse-Width Modulator (PWM)

Controller and Output Voltage Monitor

Features

• Drives N-Channel MOSFET

The HIP6008 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

HIP6008 integrates all of the control, output adjustment,

monitoring and protection functions into a single package.

• Operates From +5V or +12V Input

• Simple Single-Loop Control Design

- Voltage-Mode PWM Control

• Fast Transient Response

- High-Bandwidth Error Ampliﬁer

- Full 0% to 100% Duty Ratio

The output voltage of the converter is easily adjusted and

precisely regulated. The HIP6008 includes a 4-Input Digital-

to-Analog Converter (DAC) that adjusts the output voltage

from 2.0VDC to 3.5VDC in 0.1V increments. The precision

reference and voltage-mode regulator hold the selected

output voltage to within ±1.5% over temperature and line

voltage variations.

• Excellent Output Voltage Regulation

- ±1.5% Over Line Voltage and Temperature

• 4 Bit Digital-to-Analog Output Voltage Selection

- Wide Range . . . . . . . . . . . . . . . . . . .2.0VDC to 3.5VDC

- 0.1V Binary Steps

The HIP6008 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%.

• Power-Good Output Voltage Monitor

• Over-Voltage and Over-Current Fault Monitors

- Does Not Require Extra Current Sensing Element

- Uses MOSFET’s r

DS(ON)

• Small Converter Size

- Constant Frequency Operation

- 200kHz Free-Running Oscillator Programmable from

50kHz to over 1MHz

The HIP6008 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 HIP6008

protects against over-current conditions by inhibiting PWM

operation. Built-in over-voltage protection triggers an

external SCR to crowbar the input supply. The HIP6008

Applications

•

Power Supply for Pentium®, Pentium Pro, PowerPC™ and

Alpha™ Microprocessors

•

High-Power 5V to 3.xV DC-DC Regulators

Low-Voltage Distributed Power Supplies

monitors the current by using the r

of the upper

DS(ON)

MOSFET which eliminates the need for a current sensing

resistor.
