Description
The GRND-90A Series are non-isolated step down dc/dc converters providing up to 90 A of output current and
designed to be compatible with the Intel VRM11 requirements. Standard features include remote on/off, over
current protection, remote sense, VR_Hot signal and a power good signal. This product also makes use of
adaptive positioning to improve transient response performance. These products may be used almost anywhere
low-voltage silicon is being employed and a nominal 12 Vdc source is available. Typical applications include file
servers, work stations and other computing applications.

Over Current Protection
To provide protection in a fault output overload condition, the module is equipped with internal current-limiting
circuitry and can endure current limiting for a few mili-seconds. If the overcurrent condition persists beyond a few
milliseconds, the module will shut down into hiccup mode. The module operates normally when the output
current goes into specified range.

Remote Sense
This module has remote sense compensation feature. It can minimize the effects of resistance between
module’s output and load in system layout and facilitates accurate voltage regulation at load terminals or
other selected point.
1. The remote sense lines carries very little current and hence do not require a large cross-sectional area.
2. This module compensates for a maximum drop of 10% of the nominal output voltage.
3. When using remote sense compensation, all the resistance, parasitic inductance and capacitance of the
system are incorporated within the feedback loop of this module. It can make an effect on the module's
compensation, affecting the stability and dynamic response. A 0.1uF ceramic capacitor can be
connected at the point of load to de-couple noise on the sense wires.
4. Recommend the connection of remote sense compensation as below figure. There are a resistor RS+
(51.1 ohm) from Vo+ to Sense+ and a resistor RS- (51.1 ohm)) from Vo- to Sense- inside of this module.

5. If not using remote sense compensation, please connect sense directly to output at module's pin, that is,
connect sense+ to Vo+ and sense- to Vo- at module's pin, the shorter the better. See below figure.

1. This module has a power good indicator output. Power good pin used positive logic and is open collector.
2. Power good pin can sink 1mA.
3. The maximum voltage pulled up externally on Power Good pin should not exceed 5V.
4. When the output is within 10% of the VID setting, the power good pin will be pulled high.
