Notes
1 Rating is conditional on the module being 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
dearting 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
V
TT
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.
5 This is the calculated maximum. The minimum ESR limitation will
often result in a lower value. Consult Application Note 178 for
further details.
6
This is the typical ESR for all the electrolytic (non-ceramic) output
capacitance. Use 7 mΩ as the minimum when using max-ESR
values to calculate.
7 Tape and reel packaging only available on the surface-mount
versions.
8 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.
9 NOTICE: Some models do not support all options. Please contact
