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.

2

Up to 10 ms pulse period at 10% maximum duty.

3

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.

4

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.

5

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.

7

This is the typical ESR for all the electrolytic (non-ceramic) output

capacitance. Use 7 m

calculate.

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. PTHxx050YAZ. To order Pb-free (RoHS

compatible) through-hole parts replace the mounting option ‘H’ with ‘D’,

e.g. PTHxx050YAD.
