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.
