V I The negative input supply for the module, and the VDC reference for the Remote On/Off input. When powering the module from a +48-V supply, this input is connected to the 48-V return. Remote On/Off: This input controls the On/Off status of the output voltage. It is either driven low V I potential), or left open-circuit. For units identified with the NEN option, applying a logic low to this pin will enable the output. And for units identified with the PEN option, the output will be disabled. V O Adjust: Allows the output voltage to be trimmed by up or down between +10% and 20% of its nominal value. The adjustment method uses a single external resistor. Connecting the resistor between V O Adjust and V O adjusts the output voltage lower, and placing it between V O Adjust and O adjusts the output higher. The calculations for the resistance value follows industry standard formulas. For further information consult the application note on output voltage adustment. O The positive power output with respect to V O which is DC isolated from the input supply pins. If a negative output voltage is desired, O should be connected to the secondary circuit common and the output taken from V O V O The negative power output with respect to O which is DC isolated from the input supply pins. This output is normally connected to the secondary circuit common when a positive output voltage is desired. Sense(+): Provides the converter with an output sense capability to regulate the set-point voltage directly at the load. When used with Sense(-), the regulation circuitry will compensate for voltage drop between the converter and the load. The pin may be left open circuit, but connecting it to O will improve load regulation. Sense( Provides the converter with an output sense capability when used in conjunction with Sense(+) input.

www.ti.com APPLICATION INFORMATION Operating faults, these converters incorporate output overcurrent protection. Applying a load to the output that exceeds the converter's overcurrent threshold (see applicable specification) will cause the output voltage to momentarily fold back, and then shut down. Following shutdown the module will periodically attempt to automatically recover by initiating a soft-start power-up. This is often described as a hiccup mode of operation, whereby the module continues in the cycle of successive shutdown and power up until the load fault is removed. Once the fault is removed, the converter automatically recovers and returns to normal operation. Each converter incorporates protection circuitry that continually senses for an output overvoltage (OV) condition. The OV threshold is set approximately 20% higher than the nominal output voltage. If the converter output voltage exceeds this threshold, the converter is immediately shut down and remains in a latched-off state. To resume normal operation the converter must be actively reset. This can only be done by momentarily removing the input power to the converter. For fail-safe operation and redundancy, the OV protection uses circuitry that is independent of the converter s internal feedback loop. Overtemperature protection is provided by an internal temperature sensor, which closely monitors the temperature of the converter s printed circuit board (PCB). If the sensor exceeds a temperature of approximately 105 the converter will shut down. The converter will then automatically restart when the sensed temperature drops back to approximately When operated outside its recommended thermal derating envelope (see data sheet SOA curves), the converter will typcially cycle on and off at intervals from a few seconds to one or two minutes. This is to ensure that the internal components are not permanently damaged from excessive thermal stress. The Undervoltage lockout (UVLO) is designed to prevent the operation of the converter until the input voltage is at the minimum input voltage. This prevents high start-up current during normal power-up of the converter, and minimizes the current drain from the input source during low input voltage conditions. The UVLO circuitry also overrides the operation of the Remote On/Off control. These converters incorporate electrical isolation between the input terminals (primary) and the output terminals (secondary). All converters are production tested to a withstand voltage of 1500 VDC. This specification complies with UL60950 and EN60950 and the requirements for operational isolation. This allows the converter to be configured for either a positive or negative input voltage source. The data sheet Pin Descriptions section provides guidance as to the correct reference that must be used for the external control signals. The converter is not internally fused. For safety and overall system protection, the maximum input current to the converter must be limited. Active or passive current limiting can be used. Passive current limiting can be a fast acting fuse. A 125-V fuse, rated no more than is recommended. Active current limiting can be implemented with a current limited Hot-Swap controller. Airflow may be necessary to ensure that the module can supply the desired load current in environments with elevated ambient temperatures. The required airflow rate may be determined from the Safe Operating Area (SOA) thermal derating chart (see typical characteristics). Submit Documentation Feedback

www.ti.com Differential Remote Sense PTQA430025 PTQA430033 PTQA420050 SLTS261A MAY 2006 REVISED DECEMBER 2006 The remote sense pins allows the converter to precisely regulate the DC output voltage at a remote location. This might be a power plane on an inner layer of the host PCB. Connecting Sense(+) directly to O and Sense( to V O will improve output voltage accuracy. In the event that the sense pins are left open-circuit, an internal 10- Ω resistor between each sense pin and its corresponding output prevents an excessive rise in the output voltage. For practical reasons, the amount of IR voltage compensation should be limited to 0.5 V maximum. The remote sense feature is designed to compensate for limited amounts of IR voltage drop. It is not intended to compensate for the forward drop of a non-linear or frequency dependent components that may be placed in series with the converter output. Examples of such components include OR-ing diodes, filter inductors, ferrite beads, and fuses. Enclosing these components with the remote sense connections effectively places them inside the regulation control loop, which can affect the stability of the regulator.

www.ti.com Using the Remote On/Off Function on the PTQA Series of DC/DC Converters Negative Output Enable (NEN) Positive Output Enable (PEN) PTQA430025 PTQA430033 PTQA420050 SLTS261A MAY 2006 REVISED DECEMBER 2006 For control, the PTQA series of DC/DC converters incorporate a Remote On/Off control (pin 2). This feature can be used to switch the module off without removing the applied input source voltage. When placed in the Off state, the standby current drawn from the input source is typically reduced to mA. Models using the negative enable option, the Remote On/Off (pin control must be driven to a logic low voltage for the converter to produce an output. This is accomplished by either permanently connecting pin to V I (pin 3), or driving it low with an external control signal. Table shows the input requirements of pin for those modules with the NEN option. Table On/Off Control Requirements for Negative Enable PARAMETER MIN TYP MAX V IH Disable 2.4 V V V IL Enable 0.2 V 0.8 V V o/c Open-Circuit V V I I Pin at V I 0.75 mA For those models with the positive enable (PEN) option, leaving pin open circuit, (or driving it to an equivalent logic high voltage), will enable the converter output. This allows the module to produce an output voltage whenever a valid input source voltage is applied to I with respect to V I If a logic-low signal is then applied to pin the converter output is disabled. Table gives the input requirements of pin for modules with the PEN option. Table On/Off Control Requirements for Positive Enable PARAMETER MIN TYP MAX V IH Enable 4.5 V V V IL Disable 0.2 V 0.8 V V o/c Open-Circuit V V I I Pin at V I 0.5 mA Notes: The Remote On/Off control uses V I (pin as its ground reference. All voltages are with respect to V I An open-collector device (preferably a discrete transistor) is recommended. A pull-up resistor is not required. If one is added the pull-up voltage should not exceed Caution: Do not use a pull-resistor to I (pin 1). The remote On/Off control has a maximum input voltage of Exceeding this voltage will overstress, and possibly damage, the converter The Remote On/Off pin may be controlled with devices that have a totem-pole output. This is provided the output high level voltage OH meets the module's minimum V IH specified in Table If a TTL gate is used, a pull-up resistor may be required to the logic supply voltage. The converter incorporates an undervoltage lockout (UVLO). The UVLO keeps the converter off until the input voltage is close to the minimum specified operating voltage. This is regardless of the state of the Remote On/Off control. Consult the product specification for the UVLO input voltage thresholds. Submit Documentation Feedback

Recommended Control or Remote On/Off Input Turn-On: With a valid input source voltage applied, the converter produces a regulated output voltage within ms of the output being enabled. Figure shows the output response of the PTQA430033P following the removal of the logic-low signal from the Remote On/Off (pin 2); see Figure This corresponds to the drop in V GS in Figure Although the rise-time of the output voltage is short <10 ms), the indicated delay time will vary depending upon the input voltage and the module s internal timing. The waveforms were measured with VDC input voltage, and a 10-A resistive load. Turn-Off Time: When a valid input source is removed or if the Remote On/Off (pin is used to disable the output, with no external output capacitance, the module powers down within 200 µ Figure shows that, during power down, there is a small undershoot, typically less than 300 mV (or less than a diode drop). If used to supply processor I/O voltages, the low undershoot ensures the parasitic diodes do not conduct current and potentially cause damage to external circuitry. Figure 14. Power Up Figure 15.

Adjustment is accomplished with a single external resistor that can adjust the output voltage from 20% to +10% of the nominal set-point voltage. The placement of the resistor determines the direction of adjustment, up or down, and the value of the magnitude of adjustment. Adjust Up: To increase the output voltage add a resistor, R1, between V O Adjust (pin and Sense(+) (pin 7). Adjust Down: Add a resistor, (R2), between V O Adjust (pin and Sense( (pin 5). Refer to Figure for the placement of the required resistor, or (R2). The values of [adjust up], and (R2) [adjust down], can be calculated using the following formulas. Where: Δ Amount of adjustment in V O Original set-point voltage Notes: Use only a single resistor in either the or (R2) location. Place the resistor as close to the converter as possible. If the output voltage is increased, the maximum load current must be derated according to the following equation. Where: V O Original set-point voltage V A Adjusted output voltage (measured between pins and In any instance, the load current must not exceed the converter's maximum rated output current of The overvoltage threshold is fixed, and is set approximately 20% above the nominal output voltage. Adjusting the output voltage higher reduces the voltage margin between the adjusted output voltage and the overvoltage (OV) protection threshold. This could make the module sensitive to OV fault detection, as a result of random noise and load transients. Figure 16. Submit Documentation Feedback
