ON:
Pin 3 open; or V > Vin - 0.5 V
OFF:
Pin 3 GND; or V < 0.8 V (min - 0.2 V)

See Figure 1 for safe operating curve.

A 1,500 F electrolytic input capacitor is required for proper operation.
The capacitor must be rated for a minimum of 900 mA rms of ripple
current.
4
An external output capacitor is not required for basic operation. Adding
330 F of distributed capacitance at the load will improve the transient
response.
5
1 A/s load step, 50 to 100% Iomax, Cout = 330 F.
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
152 for more details.

Tape and reel packaging only available on the surface-mount versions.

To order Pb-free (RoHS compatible) surface-mount parts replace the
mounting option ‘S’ with ‘Z’, e.g. PTH03030WAZ. To order Pb-free
(RoHS compatible) through-hole parts replace the mounting option ‘H’
with ‘D’, e.g. PTH03030WAD.
10 NOTICE: Some models do not support all options. Please contact your
local Artesyn representative or use the on-line model number search tool at

The ultra-wide output voltage trim range offers major advantages to users who
select the PTH03030. 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 PTH03030 converter
leaves the factory the output has been adjusted to the default voltage of 0.8 V.
