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 ±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 52.5% of the internal reference voltage, both

regulators are shutdown.
