Figure 9. Remote Sense Circuit Conguration
Trim adjustments greater than the specied ±5% can have an adverse affect
on the converter's performance and are not recommended. Excessive voltage
differences between VOUT and Sense, in conjunction with trim adjustment of the
output voltage, can cause the overvoltage protection circuitry to activate (see
Performance Specications for overvoltage limits). Power derating is based on
maximum output current and voltage at the converter’s output pins. Use of trim
and sense functions can cause output voltages to increase, thereby increasing
output power beyond the converter's specied rating or cause output voltages
to climb into the output overvoltage region. Therefore:
(VOUT at pins) x (IOUT) < = rated output power
Note: Resistor values are in kΩ. Adjustment accuracy is subject to resistor
tolerances and factory-adjusted output accuracy. VO = desired output voltage.
Remote Sense (Optional on 1.2-5VOUT models)
Note: The Sense and VOUT lines are internally connected through 10
: resis-
tors. Nevertheless, if the sense function is not used for remote regulation the
user should connect the +Sense to +VOUT and –Sense to –VOUT at the DC/DC
converter pins.
UHE series converters have a sense feature to provide point of use regulation,
thereby overcoming moderate IR drops in pcb conductors or cabling. The remote
sense lines carry very little current and therefore require minimal cross-sectional-
area conductors. The sense lines are used by the feedback control-loop to regu-
late the output. As such, they are not low impedance points and must be treated
with care in layouts and cabling. Sense lines on a pcb should be run adjacent to
dc signals, preferably ground. In cables and discrete wiring applications, twisted
pair or other techniques should be implemented.
UHE series converters will compensate for drops between the output voltage
at the DC/DC and the sense voltage at the DC/DC provided that:
[VOUT(+) –VOUT(–)] –[Sense(+) –Sense (–)]
d 5% VOUT
Output overvoltage protection is monitored at the output voltage pin, not
the Sense pin. Therefore, excessive voltage differences between VOUT and
Sense in conjunction with trim adjustment of the output voltage can cause the
overvoltage protection circuitry to activate (see Performance Specications
for overvoltage limits). Power derating is based on maximum output current
and voltage at the converter’s output pins. Use of trim and sense functions can
cause output voltages to increase thereby increasing output power beyond
the UHE’s specied rating or cause output voltages to climb into the output
overvoltage region. Therefore, the designer must ensure:
(VOUT at pins) × (IOUT)
d rated output power
