When the output voltage is trimmed up, output current must be derated so that the maximum output power 10W is not exceeded.
Example to decrease output voltage of NPH10S4805EiC by 0.1V: R DOWN = -2.48374 x 9.36255 - 9.36255 - 20.59761 = 203.18kΩ

SET VOLTAGE
The output voltage of all units is set to 100mV above nominal, to offset resistive losses and thus assist with worst case error calculations. For the EiC versions, this
allowance can be altered with a single ?xed resistor, connected from the trimming pin to one of the output pins.
SHUTDOWN
When the shutdown pin (SS) is shorted to the negative input, the converter will
stop. Its current consumption will then be less than 1mA at nominal supply volt-
age. The voltage must be less than 1.5V to ensure that the unit stops, and must
be able to sink at least 1mA.
The unit will restart if the control pin is left open circuit or raised to a value
close to its normal open circuit voltage. This is typically 10V. Note however, that
the unit will not meet speci?cation while a signi?cant current drain from this pin
remains.
If the shutdown pin is to be connected to a long wire, it is recommended that a
capacitor decouples the pin to the supply common in order to avoid the risk of
injecting noise into the converter circuit. A series resistor may also be helpful.
FREQUENCY CONTROL
If the primary side dc control voltage is pulled away from its open circuit
voltage, the converter frequency will be changed, approximately in proportion
to the voltage. With +8.5VDC voltage to SS pin, the typical switching frequency
will be 300kHz. If this is raised to 15VDC, the switching frequency will typically
be 510kHz. The frequency may thus be moved away from a sensitive value or
into a safe area. Deviation of at least –10% to 30% is achievable, though the
ef?ciency will decline with signi?cant changes. Also note that if the frequency
is lowered, the switching frequency component of output ripple will increase.
Since the design uses no large electrolytic capacitors, any use of a lower
frequency must allow for the effects of increased ripple. Additional external
?ltering may be required.
Values of 10nF and 1kΩ may be used.
Many NPH series converters may be switched together simply by linking the
primary control pins. The primary common pins must also be linked.
