Description

The PT3340 series is a single-output isolated DC/DC converter, housed in a 19-pin aluminum SIP package. These modules are UL, CSA, and VDE ap- proved for telecom applications, and rated at 30W or 8A. The 18V to 60V input range allows easy integration into many distributed power applications which utilize 24V bus architectures. Standard output voltages range from 1.8V to 15V, and are each adjustable by up to ±10%. Operating features include a Remote On/Off control, an under-voltage lockout (UVLO), and a differential re- mote sense. Protection features include an output current limit, short-circuit protection, and over-temperature shut- down. A 330µF output capacitor is required for proper operation.

(2) The Remote On/Off input has an internal pull-up. If it is left open circuit the module will operate when input power is appl ied. A low-leakage (<100nA) MOSFET is recommended to control this input. The open-circuit voltage is less than 10V. See application notes for int erface considerations. (3) Output capacitor values are absolute. Allowances must be made for any additional de-coupling capacitors and the total extern al capacitor tolerance. The value of external capacitance is limited due to regulator startup current requirements. Consult the factory for further det ails. (4) For operation below 0°C, the required external output capacitor must have temperature stable characteristics. E.g. Tantalum or Oscon® types. (5) See Safe Operating Area curves or contact the factory for the appropriate thermal derating.

For technical support and more information, see inside back cover or visit www.ti.com Adjusting the Output Voltage of Power Trends’ 30W Isolated DC/DC Converter Series The factory pre-set output voltage of Power Trends’ 30W series of isolated DC/DC converters may be adjusted within a nominal ±10% range. This is accomplished with the addition of a single external resistor. For the input voltage range specified in the data sheet, Table 1 gives the allowable adjustment range for each model as V o (min) and Vo (max). Adjust Up: An increase in the output voltage is obtained by adding a resistor, R2 between Vo adjust (pin 18), and -Remote Sense (pin 13). See note 4. Adjust Down: Add a resistor (R1), between Vo adjust (pin 18), and +Remote Sense (pin 19). Refer to Figure 1 and Tables 2 & 3 for both the placement and value of the required resistor, (R1) or R2. Notes: 1. Use only a single 1% resistor in either the (R1) or R2 location. Place the resistor as close to the ISR as possible. 2. Never connect capacitors to Vo adjust. Any capacitance added to the Vo adjust control pin will affect the stability of the ISR.

If the remote sense pins are not being used, the resistors (R1) and R2 can be connected to +Vout or -Vout respectively. 4. The adjusted output voltage, Va effectively sets the voltage across pins 13 and 19 (±Remote Sense). When using the remote sense pins, V out (measured directly across pins 10– 12, and 14–17) can be significantly higher than Va, and may exceed Vo (max). If Va is adjusted upward of Vo(max), the the minimum input voltage is increased by the same percentage as V out exceeds Vo(max). The values of (R1) [adjust down], and R2 [adjust up], can also be calculated using the following formulas. (R1) = Ko (Va – Vr) – Rs kΩVr (Vo – Va) R2 = Ko – Rs kΩ (Va – Vo) Where V o = Original output voltage Va = Adjusted output voltage Vr = Reference voltage (Table 1) Ko = Multiplier constant (Table 1) Rs = Series resistance (Table 1) PT3320/3340/4560/4580 Series
