PTHxx060Y
The PTHxx060Y are a new series of non-isolated dc-dc converters designed specifically
for bus termination in DDR and QDR memory applications. Operating from either a
3.3 Vdc, 5 Vdc or 12 Vdc input, the modules generate a VTT output that will source or
sink up to 10 A of current to accurately track their VREF input. VTT is the required bus
termination supply voltage, and VREF is the reference voltage for the memory and chipset
bus receiver comparators. VREF is usually set to half the VDDQ power supply voltage.
The PTHxx060Y series employs an actively switched synchronous rectifier output to
provide state of the art stepdown switching conversion. The products are small in size
and are an ideal choice where space, performance and high efficiency are desired.

Notes

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.
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 179.
An input capacitor is required for proper operation. The capacitor must
be rated for a minimum of 500 mA rms (1000 mA for 12 V input) of ripple
current. For further information, consult Application Note 179 on
capacitor selection.
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 179 for further details.
This is the typcial 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. PTHxx060YAZ. To order Pb-free (RoHS
compatible) through-hole parts replace the mounting option ‘H’ with ‘D’,
e.g. PTHxx060YAD.
NOTICE: Some models do not support all options. Please contact your
local Artesyn representative or use the on-line model number search tool at
