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 15 A of current (12 A for 12-V input) 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 PTHxx010Y series employs an actively switched synchronous rectifier output to provide state-of-the-art stepdown switching conversion. The products are small in size (1.37 in × 0.62 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. To ensure tight load regulation, an output remote sense is also provided. Package options include both throughhole and surface mount configurations.

(1) Rating is conditional on the module being directly soldered to a 4-layer PCB with 1 oz. copper. See the SOA curves or contact the factory for appropriate derating. (2) 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 the related application note. (3) An input capacitor is required for proper operation. The capacitor must be rated for a minimum a minimum of 500 mA rms( 750 mA rms for 12-V input) of ripple current. (4) 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. (5) This is the calculated maximum. The minimum ESR limitation will often result in a lower value. Consult the application notes for further guidance. (6) This is the typcial ESR for all the electrolytic (non-ceramic) output capacitance. Use 7 mΩas the minimum when using max-ESR values to calculate.

VIN The positive input voltage power node to the module, which is referenced to common GND. This is the common ground connection for the VIN and VTT power connections. It is also the 0-VDC reference GND 1, 7 for the control inputs. The module senses the voltage at this input to regulate the output voltage, VTT. The voltage at VREF is also the reference voltage for the system bus receiver comparators. It is normally set to precisely half the bus VREF driver supply voltage (VDDQ÷ 2), using a resistor divider. The Thevenin impedance of the network driving the VREF pin should not exceed 500 Ω. See the Typical DDR Application Diagram in the Application Information section for reference. This is the regulated power output from the module with respect to the GND node, and the tracking termination supply for the application data and address buses. It is precisely regulated to the voltage applied VTT to the module's VREF input, and is active active about 20 ms after a valid input source is applied to the module. Once active it will track the voltage applied at VREF. The sense input allows the regulation circuit to compensate for voltage drop between the module and the Vo Sense load. For optimal voltage accuracy Vo Sense should be connected to VTT. The Inhibit pin is an open-collector/drain negative logic input that is referenced to GND. Applying a low-level ground signal to this input turns off the output voltage, VTT. Although the module is inhibited, a voltage, VDDQ will be present at the output terminals, fed through the DDR memory. When the Inhibit is active, the input Inhibit current drawn by the regulator is significantly reduced. If the Inhibit pin is left open circuit, the module will produce an output whenever a valid input source is applied. See the Typical DDR Application Diagram in the Application Information section for reference. N/C 4, 9, 10 No connection

Ripple current, less than 160 mΩequivalent series resistance (ESR), and temperature are the major considerations when selecting input capacitors. Unlike polymer tantalum, regular tantalum capacitors have a recommended minimum voltage rating of 2 × (maximum dc voltage + ac ripple). This is standard practice to ensure reliability. For improved ripple reduction on the input bus, ceramic capacitors may used to complement electrolytic types to achieve the minimum required capacitance. For applications with load transients (sudden changes in load current), regulator response benefits from external output capacitance. The recommended output capacitance of 470 µF will allow the modue to meet its transieint response specification. (See Electrical Specifications table). For most applications, a high quality computer-grade aluminum electrolytic capacitor is adequate. These capacitors provide decoupling over the frequency range, 2 kHz to 150 kHz, and are suitable for ambient temperatures above 0°C. Below 0°C, tantalum, ceramic or Os-Con type capacitors are recommended. When using one or more nonceramic capacitors, the calculated equivalent ESR should be no lower than 4 mΩ(7 mΩusing the manufacturer’s maximum ESR for a single capacitor). A list of preferred low-ESR type capacitors are identified in Table 1. In addition to electrolytic capacitance, adding a 10-µF to 22-µF X5R/X7R ceramic capacitor to the output reduces the output ripple voltage and improve the regulator’s transient response. The measurement of both the output ripple and transient response is also best achieved across a 10-µF ceramic capacitor.

A 10-µF X5R/X7R ceramic capacitor may also be added to reduce the reflected input ripple current. The ceramic capacitor should be located between the input electrolytic and the module. Ripple current, less than 100 mΩequivalent series resistance (ESR) and temperature are major considerations when selecting input capacitors. Unlike polymer-tantalum capacitors, regular tantalum capacitors have a recommended minimum voltage rating of 2 × (max dc voltage + ac ripple). This is standard practice to ensure reliability. No tantalum capacitors were found with sufficient voltage rating to meet this requirement. At temperatures below 0°C, the ESR of aluminum electrolytic capacitors increases. For these applications, Os-Con, polymer-tantalum, and polymer-aluminum types should be considered. For applications with load transients (sudden changes in load current), regulator response benefits from external output capacitance. The recommended output capacitance of 940 µF will allow the modue to meet its transieint response specification. (See Electrical Specifications table). For most applications, a high quality computer-grade aluminum electrolytic capacitor is adequate. These capacitors provide decoupling over the frequency range, 2 kHz to 150 kHz, and are suitable for ambient temperatures above 0°C. Below 0°C, tantalum, ceramic or Os-Con type capacitors are recommended. When using one or more nonceramic capacitors, the calculated equivalent ESR should be no lower than 4 mΩ(7 mΩusing the manufacturer’s maximum ESR for a single capacitor). A list of preferred low-ESR type capacitors are identified in Table 2. In addition to electrolytic capacitance, adding a 10-µF to 22-µF X5R/X7R ceramic capacitor to the output reduces the output ripple voltage and improve the regulator’s transient response. The measurement of both the output ripple and transient response is also best achieved across a 10-µF ceramic capacitor. Above 150 kHz the performance of aluminum electrolytic capacitors is less effective. Multilayer ceramic capacitors have very low ESR and a resonant frequency higher than the bandwidth of the regulator. They can be used to reduce the reflected ripple current at the input as well as improve the transient response of the output. When used on the output, their combined ESR is not critical as long as the total value of ceramic capacitance does not exceed 300 µF. Also, to prevent the formation of local resonances, do not place more than five identical ceramic capacitors in parallel with values of 10 µF or greater. Tantalum type capacitors are most suited for use on the output bus, and are recommended for applications where the ambient operating temperature can be less than 0°C. The AVX TPS, Sprague 593D/594/595 and Kemet T495/T510 capacitor series are suggested over other tantalum types due to their higher rated surge, power dissipation, and ripple current capability. As a caution, many general purpose tantalum capacitors have considerably higher ESR, reduced power dissipation and lower ripple current capability. These capacitors are also less reliable as they have lower power dissipation and surge current ratings. Tantalum capacitors that do not have a stated ESR or surge current rating are not recommended for power applications. When specifying Os-con and polymer tantalum capacitors for the output, the minimum ESR limit are encountered well before the maximum capacitance value is reached. Table 2 identifies the characteristics of capacitors from a number of vendors with acceptable ESR and ripple current (rms) ratings. The recommended number of capacitors required at both the input and output buses is identified for each capacitor type. This is not an extensive capacitor list. Capacitors from other vendors are available with comparable specifications. Those listed are for guidance. The RMS ripple current rating and ESR (at 100 kHz) are critical parameters necessary to insure both optimum regulator performance and long capacitor life.

Table 2. Input/Output Capacitors(1) consideration for obsolescence. N/R –Not recommended. The capacitor voltage rating does not meet the minimum derated operating limits. The voltage rating of this capacitor only allows it to be used for output voltages that are equal to or less than 5.1 V. A total capacitance of 540 µF is acceptable based on the combined ripple current rating. A ceramic capacitor can be used to complement electrolytic types at the input further reduce high-frequency ripple current.

www.ti.com DESIGNING FOR VERY FAST LOAD TRANSIENTS PTH03010Y PTH05010Y PTH12010Y SLTS223A–MARCH 2004–REVISED OCTOBER 2005 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 6600 µF, the selection of output capacitors becomes more important.
