PTV03020
The PTV03020 is a non-isolated dc-dc converter from Artesyn under the Point of Load
Alliance (POLA) standard. The vertical mounting option of the PTV03020 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 DSP’s, FPGA’s
and ASIC’s requiring controlled power-up and power-down. The PTV03020 has an input
voltage of
2.95 Vdc to 3.6 Vdc
and offers a wide 0.8 Vdc to 2.5 Vdc output voltage range
with up to 18 A output current, which allows for maximum design flexibility and a pathway
for future upgrades.
All specifications are typical at nominal input, full load at 25 °C unless otherwise stated

Output Voltage Adjustment of the PTV03020 Series
The ultra-wide output voltage trim range offers major advantages to users who
select the PTV03020. 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 PTV03020 converter
leaves the factory the output has been adjusted to the default voltage of 0.8 V

A 680 µF electrolytic input capacitor is required for proper operation as
well as a 2 2µF high-frequency ceramic capacitor. The electrolytic
capacitor must be rated for a minimum of 750 mA rms of ripple current.
4
An external output capacitor is not required for basic operation. Adding
33 0µF of distributed capacitance at the load will improve the transient
response.

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
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
module’s output held off using the Inhibit pin. Refer to Application Note
197 for more details.
8
The set-point voltage tolerance is affected by the tolerance and stability
of Rset. The stated limit is unconditionally met if Rset has a tolerance of
1% with 100/
ºC or better temperature stability.
9
To order Pb-free (RoHS compatible) through-hole parts replace the
mounting option ‘H’ with ‘D’, e.g. PTV03020WAD.
