ISL6529A
Dual Regulator–Synchronous Rectified
Buck PWM and Linear Power Controller
The ISL6529A provides the power control and protection for
two output voltages in high-performance graphics cards and
other embedded processor 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 ISL6529A provides
both a regulated high current, low voltage supply and an
independent, lower current supply integrated in an 14-lead
SOIC package. The controller is ideal for graphic card
applications where regulation of both the graphics
processing unit (GPU) 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
±
1%
over
line, load, and temperature ranges for the
ISL6529AC and
±
2% for the ISL6529C. 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 51.5% of the nominal output level, both converters are
shutdown.

NOTE: Intersil Pb-free products employ special Pb-free material
sets; molding compounds/die attach materials and 100% matte tin
plate termination finish, which are RoHS compliant and compatible
with both SnPb and Pb-free soldering operations. Intersil Pb-free
products are MSL classified at Pb-free peak reflow temperatures that
meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
