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 2.5 Vdc. When the PTH03020 converter leaves the factory the output has been adjusted to the default voltage of 0.8 V. NNootteess EFFICIENCY TABLE (I = 10 A) O 1 Remote ON/OFF. Positive Logic OUTPUT VOLTAGE EFFICIENCY ON: Pin 3 open or V > Vin - 0.5 V OFF: Pin 3 GND or V < 0.8 V (min - 0.2 V) Vo = 1.0 V 88% 2 See Figure 1 for safe operating curve. 3 A 1,000 F electrolytic input capacitor is required for proper operation. Vo = 1.2 V 90% The capacitor must be rated for a minimum of 700 mA rms of ripple current. Vo = 1.5 V 91% 4 An external output capacitor is not required for basic operation. Adding 330 F of distributed capacitance at the load will improve the transient Vo = 1.8 V 93% response. 5 1 A/s load step, 50 to 100% I , C = 330 F. omax out Vo = 2.0 V 95% 6 If utilized Vout will track applied voltage by 0.3 V (up to Vo set point). 7 The pre-bias start-up feature is not compatible with Auto-Track. This is Vo = 2.5 V 95% because when the module is under Auto-Track control, it is fully active and will sink current if the output voltage is below that of a back-feeding source. Therefore to ensure a pre-bias hold-off, one of the following two techniques must be followed when input power is first applied to the module. The Auto-Track function must either be disabled, or the modules output held off using the Inhibit pin. Refer to Application Note 151 for more details. 8 Tape and reel packaging only available on the surface-mount versions. 9 To order Pb-free (RoHS compatible) surface-mount parts replace the mounting option S with Z, e.g. PTH03020WAZ. To order Pb-free (RoHS compatible) through-hole parts replace the mounting option H with D, e.g. PTH03020WAD. 10 NOTICE: Some models do not support all options.
