Single‐Phase Voltage Regulator with SVID Interface for Computing Applications

Favorite

Overview

The NCP81568 is a high−performance, low−bias current, single−phase single rail regulator with integrated power MOSFETs intended to support a wide range of computing applications. The device is able to deliver up to 20.25A TDC, 40A ICCMAX output current on an adjustable output with SVID interface. Operating in high switching frequency allows employing small size inductor and capacitors. The controller makes use of onsemi’s patented high performance RPM operation. RPM control maximizes transient response while allowing for smooth transitions between discontinuous−frequency−scaling operation and continuous−mode full−power operation. The NCP81568 has an ultra−low offset current monitor amplifier with programmable offset compensation for high−accuracy current monitoring.
