Operating from either a 3.3-V, 5-V or 12-V input, the modules generate a VTT output that will source or sink up to 6 A of current (8 A transient) 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. Both 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 (0.87 in × 0.5 in), and are an ideal choice where space, performance, and high efficiency are desired, along with the convenience of a ready-to-use module. Operating features include an on/off inhibit and output over-current protection (source mode only). The on/off inhibit feature allows the VTT bus to be turned off to save power in a standby mode of operation. Package options include both throughhole and surface mount configurations.

See the SOA curves or contact the factory for appropriate derating. The PTH03050Y and PTH05050Y require no derating up to 85°C operating temperature and natural convection airflow. Up to 10 ms pulse period at 10% maximum duty. The minimum 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. 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.

Capacitor suppliers may recommend alternative part numbers because of limited availability or obsolete products. In some instances, the capacitor product life cycle may be in decline and have short-term consideration for obsolescence. RoHS, Lead-free and Material Details Please consult capacitor suppliers regarding material composition, RoHS status, lead-free status, and manufacturing process requirements. Component designators or part number deviations can occur when material composition or soldering requirements are updated. N/R – Not recommended. The capacitor voltage rating does not meet the minimum operating limits. A total capacitance of 470 µF is acceptable based on the combined ripple current rating. Ceramic capacitors are recommended to complement electrolytic types at the input and to reduce high-frequency ripple current. www.ti.com PTH03050Y PTH05050Y PTH12050Y SLTS221A – MARCH 2004 – REVISED OCTOBER 2005 Designing for Very Fast Load Transients The transient response of the DC/DC converter has been characterized using a load transient with a di/dt of 1 A/µs. The typical voltage deviation for this load transient is given in the data sheet specification table using the optional value of output capacitance. As the di/dt of a transient is increased, the response of a converter's regulation circuit ultimately depends on its output capacitor decoupling network. This is an inherent limitation with any DC/DC converter once the speed of the transient exceeds its bandwidth capability. If the target application specifies a higher di/dt or lower voltage deviation, the requirement can only be met with additional output capacitor decoupling. In these cases special attention must be paid to the type, value and ESR of the capacitors selected. If the transient performance requirements exceed that specified in the data sheet, or the total amount of load capacitance is above 3300 µF, the selection of output capacitors becomes more important. 11 PTH03050Y PTH05050Y PTH12050Y SLTS221A – MARCH 2004 – REVISED OCTOBER 2005 TAPE AND REEL SPECIFICATION 12 www.ti.com PTH03050Y PTH05050Y PTH12050Y www.ti.com SLTS221A – MARCH 2004 – REVISED OCTOBER 2005 TRAY SPECIFICATION 13 PACKAGE OPTION ADDENDUM www.ti.com 4-Apr-2022 PACKAGING INFORMATION Orderable Device Status (1) Package Type Package Pins Package Drawing Qty Eco Plan (2) Lead finish/ Ball material MSL Peak Temp Op Temp (°C) (3) (4/5) (6) PTH03050YAH ACTIVE ThroughHole Module EUU 6 56 RoHS Exempt & Green SN N / A for Pkg Type -40 to 85 PTH03050YAS ACTIVE Surface Mount Module EUV 6 56 Non-RoHS & Green SNPB Level-1-235C-UNLIM/ Level-3-260C-168HRS -40 to 85 PTH03050YAST ACTIVE Surface Mount Module EUV 6 250 Non-RoHS & Green SNPB Level-1-235C-UNLIM/ Level-3-260C-168HRS -40 to 85 PTH03050YAZ ACTIVE Surface Mount Module EUV 6 56 RoHS (In Work) & Green SNAGCU Level-3-260C-168 HR -40 to 85 PTH05050YAH ACTIVE ThroughHole Module EUU 6 56 RoHS (In Work) & Green (In Work) SN N / A for Pkg Type -40 to 85 PTH05050YAS ACTIVE Surface Mount Module EUV 6 56 Non-RoHS & Green SNPB Level-1-235C-UNLIM/ Level-3-260C-168HRS -40 to 85 PTH05050YAZ ACTIVE Surface Mount Module EUV 6 56 RoHS (In Work) & Green SNAGCU Level-3-260C-168 HR -40 to 85 PTH05050YAZT ACTIVE Surface Mount Module EUV 6 250 RoHS (In Work) & Green SNAGCU Level-3-260C-168 HR -40 to 85 PTH12050YAH ACTIVE ThroughHole Module EUU 6 56 RoHS Exempt & Green (In Work) SN N / A for Pkg Type -40 to 85 PTH12050YAS ACTIVE Surface Mount Module EUV 6 56 Non-RoHS & Green (In Work) SNPB Level-1-235C-UNLIM/ Level-3-260C-168HRS -40 to 85 PTH12050YAST ACTIVE Surface Mount Module EUV 6 250 Non-RoHS & Green (In Work) SNPB Level-1-235C-UNLIM/ Level-3-260C-168HRS -40 to 85 PTH12050YAZ ACTIVE Surface Mount Module EUV 6 56 RoHS (In Work) & Green (In Work) SNAGCU Level-3-260C-168 HR -40 to 85 PTH12050YAZT ACTIVE Surface Mount Module EUV 6 250 RoHS (In Work) & Green (In Work) SNAGCU Level-3-260C-168 HR -40 to 85 (1) The marketing status values are defined as follows: ACTIVE: Product device recommended for new designs.
