NEW Product

• 3.3 Vdc, 5 Vdc or 12 Vdc input voltage

• DDR and QDR compatible

• ON/OFF inhibit (for V standby)

• Under-voltage lockout

• Operating temperature range: -40 ºC to +85 ºC

• Efficiencies up to 88%

• Output overcurrent protection (non-latching, auto-reset)

• Point-of-Load-Alliance (POLA) compatible

• Available RoHS compliant

The PTHxx050Y 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 V_TToutput that will

source or sink up to 6 A of current to accurately track their V_REFinput. V_TTis the

required bus termination supply voltage, and V_REFis the reference voltage for the

memory and chipset bus receiver comparators. V_REFis usually set to half the V_DDQ

power supply voltage. The PTHxx050Y 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.
