Remote voltage sense

Remote voltage sense
The device embeds a Remote Sense Buffer to sense remotely the regulated voltage without
any additional external components. In this way, the output voltage programmed is regulated
between the remote buffer inputs compensating motherboard or connector losses. It senses
the output voltage remotely through the pins FBR and FBG (FBR is for the regulated voltage
sense while FBG is for the ground sense) and reports this voltage internally at VSEN pin
with unity gain eliminating the errors. Keeping the FBR and FBG traces parallel and guarded
by a power plane results in common mode coupling for any picked-up noise.
If remote sense is not required, it is enough connecting the resistor RFB directly to the
regulated voltage: VSEN becomes not connected and still senses the output voltage
through the remote buffer. In this case the FBG and FBR pins must be connected anyway to
the regulated voltage (See Figure 10).
Warning:
The remote buffer is included in the trimming chain in order
to achieve ±0.5% accuracy (0.6% for the AMD DAC) on the
output voltage when the RB is used: eliminating it from the
control loop causes the regulation error to be increased by
the RB offset worsening the device performances.
