Application Notes continued
PT4310 Series
Using the Remote On/Off Function on the
PT4310 Isolated Dual Output DC/DC Converters
For applications requiring output voltage On/Off control,
the PT4310 DC/DC converter series incorporates a
“Remote On/Off” control (pin 11). This feature can be used
when there is a requirement for the module to be switched
off without removing the applied input source voltage.
The converter operates normally with Pin 11 open-circuit,
and produces a regulated output voltage when a valid
source voltage is applied to +Vin (pin 18), with respect
to –Vin (pin 17). When a low-level 1 ground signal is
applied to pin 11, the converter output will be turned off.
Figure 1 shows an application schematic, which details
the typical use of the Remote On/Off function. Note the
discrete transistor (Q1). The control pin has its own
internal pull-up, and must be controlled with an open-
collector or open-drain device (See notes 2 & 3). Table 1
gives the input requirements.
When placed in the “Off” state, the standby current drawn
from the input source is typically reduced to less than 1mA.

Notes:
1. The Remote On/Off control uses –Vin (pin 17) as its
ground reference. All voltages specified are with respect
to –Vin.
2. Use an open-collector device (preferably a discrete
transistor) for the Remote On/Off input. Do not connect
a pull-up resistor directly to pin 11.
3. The Remote On/Off pin may be controlled with devices that
have a totem-pole output providing that a blocking
diode is used. The blocking diode is required to prevent
current from being injected into On/Off control pin.
Note: For TTL devices a pull-up may be required on the
cathode side of the blocking diode. This is to guarantee a
minimum enable voltage at pin 11 (See Figure 1).
4. The PT4310 converters incorporate an “Under-
Voltage Lockout” (UVLO). The UVLO will keep the
module off when the input voltage to the converter is
low, regardless of the state of the Remote On/Off
control. Table 2 gives the UVLO input voltage
thresholds.
Figure 1
Turn-On Time:
In the circuit of Figure 1, turning Q1 on applies
a low-voltage to pin 11 and disables the converter output.
Correspondingly, turning Q1 off allows the converter to
power up and produce a regulated output voltage within
50ms. Although the rise-time of the output is short (<1ms),
the delay time will vary depending upon the input voltage
and the module’s internal timing. Figure 2 shows response
of the +5-V output from the PT4311 (±5.0V), following
the turn-off of Q1 at time t =0. The waveform was
measured with a 48Vdc input voltage, and 0.25-Adc
resistive load at both the positive and negative outputs.
