Remote ON/OFF. Positive Logic
ON:
Pin 3 open; or V > Vin - 0.5 V
OFF:
Pin 3 GND; or V < 0.8 V (min - 0.2 V).
2
See Figure 1 for safe operating curve.
3
A 100 µF electrolytic input capacitor is required for proper operation. The
capacitor must be rated for a minimum of 300 mA rms of ripple current.
4
An external output capacitor is not required for basic operation. Adding
100 µF of distributed capacitance at the load will improve the transient
response.
5
1 A/µs load step, 50 to 100% Iomax, Cout = 100 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
158 for more details
.
8
Tape and reel packaging only available on the surface-mount versions.
9
To order Pb-free (RoHS compatible) surface-mount parts replace the
mounting option ‘S’ with ‘Z’, e.g. PTH05050WAZ. To order Pb-free
(RoHS compatible) through-hole parts replace the mounting option ‘H’
with ‘D’, e.g. PTH05050WAD.
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 PTH05050. 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 PTH05050 converter
leaves the factory the output has been adjusted to the default voltage of 0.8 V.
