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 PTH03010 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.

Vo = 2.0 V 92% 7 The pre-bias start-up feature is not compatible with Auto-Track . This is because when the module is under Auto-Track control, it is fully active Vo = 2.5 V 93% 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 150 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. PTH03010WAZ. To order Pb-free (RoHS compatible) through-hole parts replace the mounting option H with D, e.g. PTH03010WAD. 10 NOTICE: Some models do not support all options.
