Application Notes
PT4210 Series
Using the Remote On/Off Function on the
PT4210 Isolated 7W DC/DC Converters
Applications requiring output voltage On/Off control, the
PT4210 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 functions normally with Pin 11 open-circuit,
providing a regulated output voltage when a valid source
voltage is applied to +Vin (pin 18), with respect to –V in
(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 opencollector or open-drain device (See notes 2 & 3). Table 1
gives the input requirements.

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 (See Figure 1). 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).
or similar low-leakage PIN diode
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 pin 11 to be pulled
high by an internal pull-up resistor. The converter produces a
regulated output voltage within 50ms. Although the risetime 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 shows an example of the output
response for a PT4213 (5.0V), following the turn-off of
Q1 at time t =0. The waveform was measured with a 48Vdc
input voltage, and 1.2Adc resistive load.
Figure 2
VO (2V/Div)
4. The PT4210 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.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability
information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)
