tible to noise pickup when connected to long conductors in noisy environments.
In such cases, a 0.22µF capacitor between trim and –V
reduce this long lead effect.
On/Off Control
The input-side, remote On/Off Control function (pin 2) can be ordered to operate
with either polarity:
are enabled when pin 2 is left open (or is pulled high, applying +3.5V to +13.5V
with respect to –Input, pin 1) as per Figure 8. Positive-polarity devices are
disabled when pin 2 is pulled low (0 to 0.8V with respect to –Input).
is left open (or pulled high, applying +3.5V to +13.5V), and on when pin 2 is
pulled low (0 to 1V) with respect to –Input as shown in Figure 9.
mechanical relay or an open-collector/open-drain drive circuit (optically isolated
if appropriate). The drive circuit should be able to sink appropriate current (see
Performance Specifications) when activated and withstand appropriate voltage
when deactivated. Applying an external voltage to pin 2 when no input power is
applied to the converter can cause permanent damage to the converter.
The Trim pin (pin 6) is a relatively high impedance node that can be suscep-
Positive (no suffix): standard models are equipped with Positive-polarity and
Negative (“N” suffix): Optional Negative-polarity devices are off when pin 2
Dynamic control of the remote on/off function is best accomplished with a
