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,...
