ISL6567
Multipurpose Two-Phase Buck PWM Controller with Integrated MOSFET Drivers

The ISL6567 two-phase synchronous buck PWM control IC
provides a precision voltage regulation system for 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 interleaving inherent to this topology.
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.
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
rDS(ON) sensing for channel current balance, dynamic voltage
positioning, and overcurrent protection. Channel current
balancing is automatic and accurate with the integrated
current-balance control system. Overcurrent protection can be
tailored to various application with no need for additional
parts.
