dc-dc converters non-isolated ddr/qdr memory bus termination module 1 new product file name: pthxx010y.pdf rev (02): 19 dec 2005 2 year warranty all specifications ar e typical at nominal input, v ref = 1.25 v , full load at 25 c unless otherwise stated. c in , c o1 and c o2 = typical value specifica tions the pthxx010y 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 tt output that will sour ce or sink up to 15 a of current to accurately track their v ref input. v tt is the required bus termination supply voltage, and v ref is the reference voltage for the memory and chipset bus receiver comparators. v ref is usually set to half the v ddq power supply voltage. the pthxx010y series employs an actively switched synchr onous r ectifier output to provide state of the art stepdown switching conversion. the products are small in size and ar e an ideal choice wher e space, per for mance and high efficiency are desired. ? v tt bus termination output (output the system v ref ) ? 15 a output current ? 3.3 vdc, 5 vdc or 12 vdc input voltage ? ddr and qdr compatible ? on/off inhibit (for v tt standby) ? under-voltage lockout ? operating temperature range: -40 o to +85 ? ? efficiencies up to 91% ? output overcurrent protection (non-latching, auto-reset) ? point-of-load-alliance (pola) compatible ? available rohs compliant pthxx010y 3.3/5/12 vin single output output specifications output current (over ? ref range) pth03010y and pth05010y ?5 a (see note 1) pth12010y 12 a t racking range for v ref 0.55-1.8 vdc t racking tolerance to v ref (v tt - v ref ) -10 mv to +10 mv (over line, load and temperature) ripple and noise 20 mhz bandwidth 20 mv pk-pk load transient response 30 ? settling time (see note 4) overshoot/undershoot 30 mv typ. output capacitance: non-ceramic values pth03010y 470 ? typ., 8,200 ? max.
