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.
•18Aoutput current
•3.3 Vin input voltage
•Wide-output voltage adjust (0.8 Vdc to 2.5 Vdc)
•Auto-track™ sequencing*
•Pre-bias start-up
•Efficiencies up to 96%
•Output ON/OFF inhibit
•Output voltage sense
•Vertical through-hole mounting
•Point-of-Load-Alliance (POLA) compatible
•Undervoltage lockout
•Available RoHS compliant

2See Figure 1 for safe operating curve.
3A 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.
4An external output capacitor is not required for basic operation. Adding
33 0µF of distributed capacitance at the load will improve the transient
response.
51A/µs load step, 50 to 100% Iomax, C3 = 330 µF.
6If utilized Vout will track applied voltage by ±0.3 V (up to Vo set point).
7The 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.
8The 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.
9To order Pb-free (RoHS compatible) through-hole parts replace the
mounting option ‘H’ with ‘D’, e.g. PTV03020WAD.

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
