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.

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.
