ISL6549
Single 12V Input Supply Dual Regulator
Synchronous Rectified Buck PWM and
Linear Power Controller
The ISL6549 provides the power control and protection for
two output voltages in high-performance applications. The
dual-output controller drives two N-Channel MOSFETs in a
synchronous rectified buck converter topology and one
N-Channel MOSFET in a linear configuration. The controller is
ideal for applications where regulation of both the processing
unit and memory supplies is required.
The synchronous rectified buck converter incorporates
simple, single feedback loop, voltage-mode control with fast
transient response. Both the switching regulator and linear
regulator provide a maximum static regulation tolerance of
?SPAN class="pst ISL6549CRZR5213_2462365_4">1% over line, load, and temperature ranges. Each output is
user-adjustable by means of external resistors.
An integrated soft-start feature brings both supplies into
regulation in a controlled manner. Each output is monitored
via the FB pins for undervoltage events. If either output drops
below 75% of the nominal output level, both converters are
shut off and go into retry mode.
The ISL6549 is available in a 14 Ld SOIC package,
16 Ld QSOP, or 16 Ld 4x4 QFN packages.
