When a fault impedance is applied to one output, the module initially limits the output current of that output to approximately 150% of the maximum current rating. If the fault persists for more than 20 ms the converter shuts down, forcing the voltage at both regulated outputs to simultaneously fall to zero. Following shutdown the converter periodically attempts to recover by executing a soft-start power-up. The converter will contine in a cycle of successive shutdowns and restarts until the load fault is removed. Over-Temperature Protection The PT4711 DC/DC converter has an internal temperature sensor, which monitors the temperature of the module’s internal components. If the sensed temperature exceeds a nominal 115°C, the converter will shut down. The converter will automatically restart when the sensed temperature returns to about 100°C. Under-Voltage Lock-Out Input Current Limiting 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 5 A, is recommended. Active current limiting can be implemented with a current limited “Hot-Swap” controller. Output Voltage Configurations Both outputs from the PT4711 DC/DC converter are independently regulated and isolated from each other. This allows flexibility to how the output voltages may be configured (up to the maximum allowed working voltage between the two outputs; see specification table). Figure 1-1 shows the most common ways that the outputs of the converter may be configured. They include ±Vo (Fig. 1-1a), Vo(a)/Vo(b) (Fig. 1-1b), and 2 × Vo (Fig. 1-1c). Figure 1-1; PT4711 Output Voltage Configurations +Vo1 DC/DC Module –Vo1 The Under-Voltage Lock-Out (UVLO) circuit prevents operation of the converter whenever the input voltage to the module is insufficient to maintain output regulation. The UVLO has approximately 2 V of hysterisis. This is to prevent oscillation with a slowly changing input voltage. Below the UVLO threshold the module is off and the enable control inputs, EN1 and EN2 are inoperative. Primary-Secondary Isolation The PT4711 DC/DC converter incorporates electrical isolation between the input terminals (primary) and the output terminals (secondary). All converters are production tested to a withstand voltage of 1500 VDC. The isolation complies with UL/cUL 60950 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 regulation control circuitry for these modules is located on the secondary (output) side of the isolation barrier. Control signals are passed between the primary and secondary sides of the converter. The data sheet ‘Pin Descriptions’ and ‘Pin-Out Information’ provides guidance as to which reference (primary or secondary) that must be used for each of the external control pin. +Vo2 –Vo2 14 +Vo 16 18 20 –Vo a. ±Vo Center Common +Vo1 14 +Vo(a) DC/DC Module –Vo 16 1 +Vo2 –Vo2 18 +Vo(b) 20 b. +Vo(a)/+Vo(b) +Vo1 DC/DC Module –Vo1 +Vo2 –Vo2 14 2 × Vo 16 18 20 c. 2 × +Vo For technical support and further information, visit http://power.ti.com Application Notes PT4711 Using the On/Off Enable Controls on the PT4711 Dual-Output DC/DC Converter The PT4711 is a dual-output DC/DC converter incorporates two output enable controls. EN1 (pin 4) is the Negative Enable input, and EN2 (pin 3) is the Positive Enable input. Both inputs are electrically referenced to -Vin (pin 2) on the primary or input side of the converter. A pull-up resistor is not required, but may be added if desired. Voltages of up to 70 V can be safely applied to the either of the Enable pins. pin 4 in order to enable the outputs of the converter. An example of this configuration is detailed in Figure 2. Note: The converter will only produce an output voltage if a valid input voltage is applied to ±Vin. Figure 2; Negative Enable Configuration DC/DC Module Automatic (UVLO) Power-Up 3 Connecting EN1 (pin 4) to -Vin (pin 2) and leaving EN2 (pin 3) open-circuit configures the converter for automatic power up. (See data sheet “Typical Application”). The converter control circuitry incorporates an “Under Voltage Lockout” (UVLO) function, which disables the converter until the minimum specified input voltage is present at ±Vin. (See data sheet Specifications). The UVLO circuitry ensures a clean transition during power-up and power-down, allowing the converter to tolerate a slowrising input voltage. For most applications EN1 and EN2, can be configured for automatic power-up. Positive Output Enable (Negative Inhibit) To configure the converter for a positive enable function, connect EN1 (pin 4) to -Vin (pin 2), and apply the system On/Off control signal to EN2 (pin 3). In this configuration, a low-level input voltage (-Vin potential) applied to pin 3 disables the converter outputs. Figure 1 is an example of this configuration. 4 EN 2 EN 1* BSS138 1 =Outputs On –VIN 2 –Vin On/Off Output Voltage Sequencing Both outputs from the PT4711 converter are internally sequenced to power up in unison. Figure 3-3 shows the output waveforms after the module’s output has been enabled. The converter produces a fully regulated output within 75 ms. The waveforms were measured with the output voltages configured per Figure 1-1a (for ±15-V output). A constant current load of 1.5 A was applied to both outputs, with an input source of 48 VDC.

The magnitude of each output may be trimmed higher or lower than the nominal set-point by up to 10%. The adjustment method uses a single external resistor. 1 The value of the resistor determines the magnitude of adjustment, and the location of the resistor determines the direction of adjustment (increase or decrease). The resistor values can be calculated using a formula (see below). Alternatively the resistor value may be selected directly from the values given in Table 2-2. The placement of each resistor is as follows. Adjust Down: To decrease the magnitude of the output voltage, add a resistor (R2), between the appropriate Vox Adj (Vo1 Adj or Vo2 Adj,) and the respective +Vox voltage rail. See Figure 2-1(b) and Table 2-1 for the resistor placement and pin connections. Adjust Up: To increase the magnitude of the output voltage, add a resistor R1 between the appropriate Vo x Adj (‘Vo1 Adj’ or ‘Vo2 Adj’) and the respective -Vo x voltage rail. See Figure 2-1(a) and Table 2-1 for the resistor placement and pin connections.

Note that the equation for R1 [Adjust Up] is different to that for (R2) [Adjust Down]. Notes: 1. Use only a single 1% (or better) tolerance resistor in either the R1 or (R2) location to adjust a specific output. Place the resistor as close to the ISR as possible. 2. Never connect capacitors to any of the ‘Vox Adj’ pins. Any capacitance added to these control pins will affect the stability of the respective regulated output.
