1 Remote ON/OFF. Positive logic
ON: Pin 3 open; or V > Vin - 0.5 V
OFF: Pin 3 GND; or V < 0.6 V
2 See Figure 1 for safe operating curve.
3 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 r
ms of ripple current.
4 An exter
nal output capacitor is not r
equir
ed for basic operation. Adding
33 0µF of distributed capacitance at the load will improve the transient
response.
5 1A/µs load step, 50 to 100% I
omax
, C3 = 330 µF.
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
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 R
set
. The stated limit is unconditionally met if R
set
has a tolerance of
1% with 100/
ºC or better temperatur
e stability
.
9 To 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
