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.
