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. 2 YEAR WARRANTY All specifications are typical at nominal input, VREF = 1.25 V, full load at 25 C unless otherwise stated.

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/s load step, -1.5 A to +1.5 A. 5 6 7 8 9 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 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.
