Description
The PT4220 power modules are a series of DC/DC converters housed in an ultra-low profile (8mm) solderable copper case. The series includes a num- ber of preset output voltages ranging from 1.3V † up to 12V, all fully approved for Telecom use. They may also be used in many other applications that require input-output isolation over an extended temperature range. The modules are an ideal choice for low-power digital and analog circuits, including DSPs and microcontrollers. The flexibility of input-output isolation also allows the output to be configured for negative voltage operation. The PT4220 series is made available in both horizontal and vertical pin con- figurations, including surface mount.

(2) The maximum output current reduces the output power of the following devices to less than 10W:- (3) The Remote On/Off (pin 1) has an internal pull-up, and if it is left open circuit the converter will operate when input powe r is applied. The open-circuit voltage is typically 5V. Refer to the application notes for interface considerations. (4) See Safe Operating Area curves or contact the factory for the appropriate derating. (5) An output capacitor is not required for proper operation. (6) The case pins on through-hole pin configurations (N & A) must be soldered. For more information see the applicable package o utline drawing.

For technical support and more information, see inside back cover or visit www.ti.com Adjusting the Output Voltage of the 10W-Rated Excalibur™ Series of Isolated DC/DC Converters The factory pre-set output voltage of Power Trends’ 10W Excalibur series of isolated DC-DC converters may be adjusted over a narrow 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 pin 10 (Vo adjust), and pins 6 & 7 (–Vout). Adjust Down: Add a resistor (R1), between pin 10 (Vo adjust) and pins 8 & 9 (+Vout). Refer to Figure 1 and Table 2 for both the placement and value of the required resistor, (R1) or R2. The values of (R1) [adjust down], and R2 [adjust up], can also be calculated using the following formulas. (R1) = 56.2 (V a – 1.225) – Rs kΩ Vo – Va Table 1 DC/DC CONVERTER ADJUSTMENT RANGE AND FORMULA PARAMETERS Series Pt # 24V Bus PT4247 PT4246 PT4241 PT4245 PT4242 PT4243 PT4244 48V Bus PT4227 PT4226 PT4221 PT4225 PT4222 PT4223 PT4224 Rated Current 3 3A 3A 3A 3A 3A 2A 0.85A Figure 1 PT4220/4240 +Vout -Vout +Vin -Vin Remote On/Off V o(adj) 5 8, 9 6, 7 10 L O A D +V in -Vin +V O –V O (R1) Adj Down Adjust Up R2 = 68.845 – Rs kΩ Va – Vo Where, V o = Original output voltage Va = Adjusted output voltage Rs = Internal resistance (Table 1) 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. 3. The output power is limited to 10W. If the output voltage is increased, the maximum load current must be derated according to the following equation. Io(max) = 10 Va In any instance, the load current must not exceed the converter’s rated current (See Table 1). PT4220/4240 Series
