ISL6529, ISL6529A
Dual Regulator–Synchronous Rectified
Buck PWM and Linear Power Controllers
The ISL6529, ISL6529A provide the power control and
protection for two output voltages in high-performance
graphics cards and other embedded processor applications.
The dual-output controllers drive two N-Channel MOSFETs
in a synchronous rectified buck converter topology and one
N-Channel MOSFET in a linear configuration. The ISL6529,
ISL6529A provide both a regulated high current, low voltage
supply and an independent, lower current supply integrated
in a 14-lead SOIC package. The controllers are ideal for
graphic card applications where regulation of both the
graphics processing unit (GPU) and memory supplies is
required.
The synchronous rectified buck converters incorporate
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
±
2% 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 51.5% of the nominal output level, both
converters are shut down.

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.
