The VRNE-60ED10/20 has dual non-isolated step down DC/DC
converters providing up to 40A/ 5A (VDD/ VTT) of output current and
designed to be compatible with the Intel VRM12 requirements.
Standard features include remote on/off, over current protection,
remote sense, Power Good and VR_ Hot signal. These products may
be used almost anywhere low-voltage silicon is being employed and a
nominal 12V source is available. Typical applications include file
servers, work stations and other computing applications.

NOTE: 1. All specifications are typical at nominal input, full load at

2. Only power recycle and re-enable can clear the OCP latch.
3. The interval in hiccup mode is about 56mS. The OCP exit
when the output current is lower than the limit.
4. Because Vtt output tracks half of Vdd output, the Vtt output
is also latched if Vdd rail OCP is triggered.

VRNE-60ED10/20 Series
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. If the unit is already trimmed up, the available remote sense compensation range should be correspondingly reduced. The total
voltage increased by trim and remote sense should not exceed 10% of the nominal output voltage.
4. When using remote sense compensation, all the resistance, parasitic inductance and capacitance of the system are incorporated
within the feedback loop of this module. The can make an effect on the module's compensation, affecting the stability and dyn.
5. Recommend the connection of remote sense compensation as below figure. There are a resistor RS+ (10 Ω) from Vo+ to Sense+
and a resistor RS- (10 Ω)) from Vo- to Sense- inside of this module.
6. 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. Each rail has a power good indicator output in this module (J1-21, J1-22), to indicate this rail is ready to supply regulated voltage.
Power good pins use positive logic and are open collector.
2. For the VDD output, the signal is asserted high at the end of turn-on indicating that the output has reached the boot voltage.
3. For the VTT output, the signal is asserted high when the output is within 9% of normal output regulation point after soft start with 6%
hysteresis.
