Notes
1
Rating is conditional on the module being directly soldered to a 4 layer
PCB with 1 oz. copper. See the SOA curves or contact the factory for
appropriate derating. The PTH03050Y and PTH05050Y require no
derating up to 85 °C operating temperature and natural convection
airflow.
Up to 10 ms pulse period at 10% maximum duty.
This control pin has an internal pull-up to the input voltage Vin. If it is left
open-circuit the module will operate when input power is applied. A small
low-leakage (<100 nA) MOSFET is recommended for control. For further
information, consult Application Note 178.
An input capacitor is required for proper operation. The capacitor must
be rated for a minimum of 300 mA rms (750 mA rms for 12 V input) of
ripple current.
The typical value of external output capacitance value ensures that VTT
meets the specified transient performance requirements for the memory
bus terminations. Lower values of capacitance may be possible when the
measured peak change in output current is consistently less than 3 A.
Test conditions were 15 A/µs load step, -1.5 A to +1.5 A.
This is the calculated maximum. The minimum ESR limitation will often
result in a lower value. Consult Application Note 178 for further details.

This is the typical ESR for all the electrolytic (non-ceramic) output
capacitance. Use 7 m
Ω
as the minimum when using max ESR values to
calculate.

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. PTHxx050YAZ. To order Pb-free (RoHS
compatible) through-hole parts replace the mounting option ‘H’ with ‘D’,
e.g. PTHxx050YAD.
