Description
The V7NB-60A Series are non-isolated step down DC/DC converters providing up to 60A of peak output current
and designed to be compatible to the Intel VRM 9 and VRM10 VID codes (maximum output voltage = 1.6V).
Standard features include remote on/off, over current protection, remote sense and a power good signal. This
product also makes use of adaptive positioning to improve transient response performance. Typical
applications include file servers, work stations and other computing applications.

Notes:
1. Consult factory for trim option.
2. Pin 51 is VID5 for VRM10 applications. If
you are not using this pin, leave it floating.
Consult factory for VRM10 VID table.
3. Current share is not implemented on this
module. Consult factory for applications requiring
current share.
4. Module leads, header, and any portion of the
component that is exposed directly to
molten solder will withstand a temperature of 260
degrees C for a minimum of 10 seconds.
Component sections not exposed directly to the
solder will withstand 150 degrees C. Lead
Solderability meets ANSI/J-STD-002.

Trim
Logic level inputs used to set the output voltage, refer to VID table
below. Connect these pins either to open-drain outputs with or
without external pull-up resistors or to active-pull-up outputs. VID0VID5 have 20uA internal pull-up current sources that diminish to
zero as the voltage rises above 2.5V. These inputs can be pulled up
as high as 5.3V. See note 2.
Optional trim pin, used to adjust the output voltage. See note 1.
VO-sen+
VO-sen-
The open drain power good signal detects output under voltage
only. It transitions to the high state after soft start has completed. If
the output voltage falls below 74% of the nominal VID voltage, the
signal is de-asserted.
Remote voltage sense lines. Connect these at the point of load, to
VO+ and VO- respectively.
VO-

VO+
Output voltage available to the load.
OUTEN
Logic level input used to enable the converter when high.
VRM-pres
Pin is tied to ground on module and is used by system to detect if a
VRM is present.
