Multipurpose Two-Phase Buck PWM

Controller with Integrated MOSFET

Drivers

Features

• Integrated Two-Phase Power Conversion

- Integrated 4A Drivers for High Efficiency

The ISL6567 two-phase synchronous buck PWM control IC

provides a precision voltage regulation system for

• Shunt Regulator for Wide Input Power Conversion

- 5V and Higher Bias

point-of-load and other high-current applications requiring an

efficient and compact implementation. Multi-phase power

conversion is a marked departure from single phase

converter configurations employed to satisfy the increasing

current demands of various electronic circuits. By distributing

the power and load current, implementation of multi-phase

converters utilize smaller and lower cost transistors with

fewer input and output capacitors. These reductions accrue

from the higher effective conversion frequency with higher

frequency ripple current resulting from the phase

- Up to 20V Power-Down-Conversion

• Precision Channel Current Sharing

- Loss-Less Current Sampling - Uses r

DS(ON)

• Precision Output Voltage Regulation

- ±0.6% System Accuracy Over-Temperature

(Commercial Range)

• 0.6V Internal Reference

• Full Spectrum Voltage Tracking

interleaving inherent to this topology.

- Coincidental, Ratiometric, or Offset

Outstanding features of this controller IC include an internal

0.6V reference with a system regulation accuracy of ±0.6%,

an optional external reference input, and user-adjustable

switching frequency. Precision regulation is further

enhanced by the available unity-gain differential amplifier

targeted at remote voltage sensing capability, while output

regulation is monitored and its quality is reported via a

PGOOD pin. Also included is an internal shunt regulator with

optional external connection capability which extends the

operational input voltage range. For applications requiring

voltage tracking or sequencing, the ISL6567 offers a host of

possibilities, including coincidental, ratiometric, or offset

tracking, as well as sequential start-ups, user adjustable for

a wide range of applications.

• Sequential Start-up Control

• Adjustable Switching Frequency

- 150kHz to 1.5MHz

• Fast Transient Recovery Time

• Unity-Gain Differential Amplifier

- Increased Voltage Sensing Accuracy

• Overcurrent Protection

• Overvoltage Protection

• Start-up into Pre-Charged Output

• Small, QFN Package Footprint

• Pb-Free (RoHS Compliant)

Protection features of this controller IC include overvoltage

and overcurrent protection. Overvoltage results in the

converter turning the lower MOSFETs ON to clamp the rising

output voltage. The ISL6567 uses cost and space-saving
