ISL6528
Dual Regulator - Standard Buck PWM
and Linear Power Controller
The ISL6528 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 an N-Channel MOSFET in a standard buck
topology and a NPN pass transistor in a linear configuration.
The ISL6528 provides both a regulated high current, low
voltage supply and an independent, lower current supply
integrated in an 8-lead SOIC package. The controller is ideal
for graphics card applications where both graphics
processing unit (GPU) and memory supplies are required.
The standard buck converter is a 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 ?% 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 52.5% of the internal reference voltage, both
regulators are shutdown.

NOTE: Intersil Pb-free plus anneal 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.
