The PTV05020 is a non-isolated dc-dc converter from Artesyn under the Point of Load
Alliance (POLA) standard. The vertical mounting option of the PTV05020 module provides
performance in less than 20% of the space that is required by alternative solutions. The
Auto-Track feature provides for sequencing between multiple modules, a function, which
is becoming a necessity for powering advanced silicon including DSPs, FPGAs and ASICs
requiring controlled power-up and power-down. The PTV05020 has an input voltage of
4.5 Vdc to 5.5 Vdc and offers a wide 0.8 Vdc to 3.6 Vdc output voltage range with up to
18 A output current, which allows for maximum design flexibility and a pathway for future

The ultra-wide output voltage trim range offers major advantages to users who
select the PTV05020. 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 3.6 Vdc. When the PTV05020 converter
leaves the factory the output has been adjusted to the default voltage of 0.8 V

3 A 680 F electrolytic input capacitor is required for proper operation as

well as a 22 F high-frequency ceramic capacitor. The electrolytic

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 = 1.0 V 85%
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
198 for more details.
8 The set-point voltage tolerance is affected by the tolerance and stability
of R . The stated limit is unconditionally met if R has a tolerance of
set set
1% with 100/C or better temperature stability.
9 To order Pb-free (RoHS compatible) through-hole parts replace the
mounting option H with D, e.g. PTV05020WAD.
