MPDTH***60 Series

Adjustable Non-isolated 10-Amp

POLA DC/DC Converters

OUTPUT VOLTAGE ADJUSTMENT

The output voltage may be adjusted over a limited range by connecting an

external trim resistor (Rset) between the VoutAdjust (trim) pin and Ground.

The Rset resistor must be a 1/10 Watt precision metal film type, ±1% accu-

racy or lower with low temperature coefficient, ±100 ppm/°C. or better.

Mount the resistor close to the converter with short leads.

In the tables below, the calculated resistance is given and an equivalent

using two series-connected standard value resistors. Do not exceed the

specified limits of the output voltage or the converter’s maximum power

rating when applying these resistors. Also, avoid high noise at the VoutAdjust

input. However, you should never connect any capacitors to VoutAdjust to

either Ground or Vout to prevent instability.
