Pin Length (0.140”) A = Surface-Mount Tin/Lead Solder Ball Output Voltage Adjustment of the PTH12050 Series The ultra-wide output voltage trim range offers major advantages to users who select the PTH12050. It is no longer necessary to purchase a variety of modules in order to cover different output voltages. The output voltage can be trimmed in a range of 1.2 V to 5.5 V for suffix ‘-W’ and 0.8 V to 1.8 V for suffix ‘-L’. When the PTH12050 converter leaves the factory the output has been adjusted to the default voltage of 1.2 V for the PTH12050W and 0.8V for the PTH12050L. Notes 1 Remote ON/OFF. Positive Logic ON: Pin 3 open; or V > Vin - 0.5 V OFF: Pin 3 GND; or V < 0.8 V (min - 0.2 V). 2 See Figure 1 for safe operating curve. 3 A 100 µF electrolytic input capacitor is required for proper operation. The capacitor must be rated for a minimum of 750 mA rms of ripple current. C2 = 10 µF ceramic capacitor, required for output voltages of 3.3 V and higher. 4 An external output capacitor is not required for basic operation. Adding 100 µF of distributed capacitance at the load will improve the transient response. 5 1 A/µs load step, 50 to 100% Iomax, Cout = 100 µF. 6 If utilized Vout will track applied voltage by ±0.3 V (up to Vo set point). 7 Tape and reel packaging only available on the surface-mount versions. 8 The pk-pk output ripple voltage is measured with an external 10µF ceramic capacitor. See Figure 3 Standard application schematic. 9 To order Pb-free (RoHS compatible) surface-mount parts replace the mounting option ‘S’ with ‘Z’, e.g. PTH12050WAZ. To order Pb-free (RoHS compatible) through-hole parts replace the mounting option ‘H’ with ‘D’, e.g. PTH12050WAD. 10 NOTICE: Some models do not support all options.
