Pin Length (0.140”) A = Surface-Mount Tin/Lead Solder Ball Output Voltage Code W = Wide Output Voltage Adjustment of the PTH12040W Series The ultra-wide output voltage trim range offers major advantages to users who select the PTH12040W. 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 0.8 Vdc to 5.5 Vdc. When the PTH12040W converter leaves the factory the output has been adjusted to the default voltage of 0.8 V. Notes Efficiency Table - PTH12040W (IO = 35 A) 1 The set-point voltage tolerance is affected by the tolerance and stability of Output Voltage Efficiency RSET. The stated limit is unconditionally met if RSET has a tolerance of 1% with 100 ppm/˚C or better temperature stability. Vo = 5.0 V 96% 2 This control pin has an internal pull-up to 5 V nominal. If it is left open-circuit the module will operate when input power is applied. A small low leakage Vo = 3.3 V 95% (<100 nA) MOSFET is recommended for control. For further information, consult the related application note. For further information, consult Vo = 2.5 V 93% Application Note 193. 3 A 1000 µF input capacitor is required for proper operation. The capacitor must Vo = 2.0 V 92% be rated for a minimum of 300 mA rms of ripple current. Vo = 1.8 V 91% 4 This is with a 1 A/µs loadstep, 50 to 100% Iomax, Io = 680 µF. 5 See Figures 1 and 2 for safe operating curves. Vo = 1.5 V 90% 6 When the set-point voltage is adjusted higher than 3.6 V, a 10 V minimum input voltage is recommended. Vo = 1.2 V 88% 7 A small low-leakage (<100 nA) MOSFET is recommended to control this pin. The open circuit voltage is less than 1 Vdc. Vo = 1.0 V 86% 8 These are the default voltages. They may be adjusted using the ‘UVLO Prog’ control input. Consult Application Note No. 193 for further information. Vo = 0.8 V 82% 9 To order Pb-free (RoHS compatible) surface-mount parts replace the mounting option ‘S’ with ‘Z’, e.g. PTH12040WAZ. To order Pb-free (RoHS compatible) through-hole parts replace the mounting option ‘H’ with ‘D’, e.g. PTH12040WAD. 10 NOTICE: Some models do not support all options.
