Having the termination voltage at midpoint, the power supply insures symmetry for switching times. Also, areference voltage (V REF ) that is free of any noise or voltage variations is needed for the DDR SDRAM input receiver, V REF is also equal to 1/2 V DDQ . Varying the V REF voltage will effect the setup and hold time of the memory. To comply with DDR requirements and to obtain best performance, V TT and V REF need to be tightly regulated to track 1/2 V DDQ across voltage, temperature, and noise margins. V TT should track any variations in the DC V REF value (V TT = V REF +/- 40 mV), (See Figure 4) for a DDR system level diagram.The 34712 supplies the V TT and a buffered V REF output. To ensure compliance with DDR specifications, the V DDQ line is applied to the VREFIN pin and divided by 2 internally through a precision resistor divider. This internal voltage is then used as the reference voltage for the V TT output. The same internal voltage is also buffered to give the V REFvoltage at the VREFOUT pin for the application to use without the need for an external resistor divider. The 34712 provides the tight voltage regulation and power sequencing/tracking required along with handling the DDR peak transient current requirements. Buffering the V REF output helps its immunity against noise and load changes.The 34712 utilizes a voltage mode synchronous buck switching converter topology with integrated low R DS(ON) (45 m Ω) N-channel power MOSFETs to provide a V TT voltage with an accuracy of less than ±2.0 %. It has a programmable switching frequency that allows for flexibility and optimization over the operating conditions and can operate at up to1.0 MHz to significantly reduce the external components size and cost. The 34712 can sink and source up to 3.0 A ofcontinuous current. It provides protection against output over current, overvoltage, undervoltage, and overtemperature conditions. It also protects the system from short circuitevents. It incorporates a power-good output signal to alert the host when a fault occurs.For boards that support the Suspend-To-RAM (S3) and the Suspend-To-Disk (S5) states, the 34712 offers the STBY and the SD pins respectively. Pulling any of these pins low, puts the IC in the corresponding state.By integrating the control/supervisory circuitry along with the Power MOSFET switches for the buck converter into a space-efficient package, the 34712 offers a complete, small-size, cost-effective, and simple solution to satisfy the needs of DDR memory applications.Besides DDR memory termination, the 34712 can be used to supply termination for other active buses and graphics card memory. It can be used in Netcom/Telecom applications like servers. It can also be used in desktop motherboards, game consoles, set top boxes, and high end high definition TVs.Figure 4. DDR System Level DiagramFUNCTIONAL PIN DESCRIPTIONREFERENCE VOLTAGE INPUT (VREFIN)The 34712 will track 1/2 the voltage applied at this pin.REFERENCE VOLTAGE OUTPUT (VREFOUT)This is a buffered reference voltage output that is equal to 1/2 V REFIN . It has a 10.0 mA current drive capability. This output is used as the V REF voltage rail and should be filtered against any noise. Connect a 0.1 µF, 6 V low ESR ceramic filter capacitor between this pin and the GND pin andbetween this pin and V DDQ rail. V REFOUT is also used as the reference voltage for the buck converter error amplifier.FREQUENCY ADJUSTMENT INPUT (FREQ)The buck converter switching frequency can be adjusted by connecting this pin to an external resistor divider between VDDI and GND pins. The default switching frequency (FREQ pin connected to ground, GND) is set at 1.0 MHz.SIGNAL GROUND (GND)Analog ground of the IC. Internal analog signals are referenced to this pin voltage.V DDQV DDQV TTV REFBUSDDR Memory Controller DDR Memory Input ReceiverR SR TFUNCTIONAL DESCRIPTION FUNCTIONAL PIN DESCRIPTIONINTERNAL SUPPLY VOLTAGE OUTPUT (VDDI) This is the output of the internal bias voltage regulator. Connect a 1.0 µF, 6 V low ESR ceramic filter capacitor between this pin and the GND pin. Filtering any spikes on this output is essential to the internal circuitry stable operation.OUTPUT VOLTAGE DISCHARGE PATH (VOUT) Output voltage of the Buck Converter is connected to this pin. it only serves as the output discharge path once the SD signal is asserted.ERROR AMPLIFIER INVERTING INPUT (INV) Buck converter error amplifier inverting input. Connect the VTT voltage directly to this pin.COMPENSATION INPUT (COMP)Buck converter external compensation network connects to this pin. Use a type III compensation network.INPUT SUPPLY VOLTAGE (VIN)IC power supply input voltage. Input filtering is required for the device to operate properly.POWER GROUND (PGND)Buck converter and discharge MOSFETs power ground. It is the source of the buck converter low-side power MOSFET. SWITCHING NODE (SW)Buck converter switching node. This pin is connected to the output inductor.POWER INPUT VOLTAGE (PVIN)Buck converter power input voltage. This is the drain of the buck converter high-side power MOSFET. BOOTSTRAP INPUT (BOOT)Bootstrap capacitor input pin. Connect a capacitor (as discussed on page 19) between this pin and the SW pin to enhance the gate of the high-side Power MOSFET during switching.SHUTDOWN INPUT (SD)If this pin is tied to the GND pin, the device will be in Shutdown Mode. If left unconnected or tied to the VIN pin, the device will be in Normal Mode. The pin has an internal pull up of 1.5 MΩ. This input accepts the S5 (Suspend-To-Disk) control signal.STANDBY INPUT (STBY)If this pin is tied to the GND pin, the device will be in Standby Mode. If left unconnected or tied to the VIN pin, the device will be in Normal Mode. The pin has an internal pull up of 1.5 MΩ. This input accepts the S3 (Suspend-To-RAM) control signal.POWER GOOD OUTPUT SIGNAL (PG)This is an active low open drain output that is used to report the status of the device to a host. This output activates after a successful power up sequence and stays active as long as the device is in normal operation and is not experiencing any faults. This output activates after a 10 ms delay and must be pulled up by an external resistor to a supply voltage (e.g.,V IN.).FUNCTIONAL DESCRIPTIONFUNCTIONAL INTERNAL BLOCK DESCRIPTIONFUNCTIONAL INTERNAL BLOCK DESCRIPTIONFigure 5. 34712 Internal Block DiagramINTERNAL BIAS CIRCUITSThis block contains all circuits that provide the necessary supply voltages and bias currents for the internal circuitry. It consists of:•Internal Voltage Supply Regulator: This regulator supplies the V DDI voltage that is used to drive the digital/ analog internal circuits. It is equipped with a Power-On-Reset (POR) circuit that watches for the right regulation levels. External filtering is needed on the VDDI pin. This block will turn off during the shutdown mode.•Internal Bandgap Reference Voltage: This supplies the reference voltage to some of the internal circuitry.•Bias Circuit: This block generates the bias currents necessary to run all of the blocks in the IC. SYSTEM CONTROL AND LOGICThis block is the brain of the IC where the device processes data and reacts to it. Based on the status of the STBY and SD pins, the system control reacts accordingly and orders the device into the right status. It also takes inputs from all of the monitoring/protection circuits and initiates power up or power down commands. It communicates with the buck converter to manage the switching operation and protects it against any faults.OSCILLATORThis block generates the clock cycles necessary to run the IC digital blocks. It also generates the buck converter switching frequency. The switching frequency has a default value of 1.0 MHz and can be programmed by connecting a resistor divider to the FREQ pin, between VDDI and GND pins (See Figure 1).PROTECTION FUNCTIONSThis block contains the following circuits:•Over Current Limit and Short Circuit Detection: This block monitors the output of the buck converter for over current conditions and short circuit events and alerts the system control for further command.•Thermal Limit Detection: This block monitors the temperature of the device for overheating events. If the temperature rises above the thermal shutdownthreshold, this block will alert the system control forfurther commands.•Output Overvoltage and Undervoltage Monitoring: This block monitors the buck converter output voltage toensure it is within regulation boundaries. If not, thisblock alerts the system control for further commands.CONTROL AND SUPERVISORY FUNCTIONS This block is used to interface with an outside host. It contains the following circuits:•Standby Control Input: An outside host can put the 34712 device into standby mode (S3 or Suspend-To-RAM mode) by sending a logic “0” to the STBY pin.•Shutdown Control Input: An outside host can put the 34712 device into shutdown mode (S5 or Suspend-To-Disk mode) by sending a logic “0” to the SD pin.•Power Good Output Signal PG: The 34712 can communicate to an external host that a fault hasInternal Bias System ControlOscillator Circuits& LogicControl &Protection Tracking &SupervisoryFunctionsFunctionsSequencingBuck ConverterFUNCTIONAL DESCRIPTION FUNCTIONAL INTERNAL BLOCK DESCRIPTIONoccurred by releasing the drive on the PG pin high,allowing the signal/pin to be pulled high by the external pull-up resistor.TRACKING AND SEQUENCINGThis block allows the output of the 34712 to track 1/2 the voltage applied at the VREFIN pin. This allows the V REF and V TT voltages to track 1/2 V DDQ and assures that none of them will be higher than V DDQ at any point during normal operating conditions. For power down during a shutdown (S5) mode, the 34712 uses internal discharge MOSFETs (M5 and M6 on Figure 2) to discharge V TT and V REF respectively. These discharge MOSFETs are only active during shutdown mode. Using this block along with controlling the SD and STBY pins can offer the user power sequencing capabilities by controlling when to turn the 34712 outputs on or off.BUCK CONVERTERThis block provides the main function of the 34712: DC to DC conversion from an un-regulated input voltage to a regulated output voltage used by the loads for reliable operation. The buck converter is a high performance, fixed frequency (externally adjustable), synchronous buck PWM voltage-mode control. It drives integrated 45 mΩ N-channel power MOSFETs saving board space and enhancing efficiency. The switching regulator output voltage is adjustable with an accuracy of less than ±2.0 % to meet DDR requirements. Its output has the ability to track 1/2 the voltage applied at the VREFIN pin. The regulator's voltage control loop is compensated using a type III compensation network, with external components to allow for optimizing the loop compensation, for a wide range of operating conditions. A typical Bootstrap circuit with an internal PMOS switch is used to provide the voltage necessary to properly enhance the high-side MOSFET gate.The 34712 is designed to address DDR memory power supplies. The integrated converter has the ability to both sink and source up to 3.0 A of continuous current, making it suitable for bus termination power supplies.FUNCTIONAL DEVICE OPERATIONOPERATIONAL MODESFUNCTIONAL DEVICE OPERATIONOPERATIONAL MODESFigure 6. Operation Modes DiagramMODES OF OPERATIONThe 34712 has three primary modes of operation:Normal ModeIn normal mode, all functions and outputs are fully operational. To be in this mode, the V IN needs to be within its operating range, both Shutdown and Standby inputs are high, and no faults are present. This mode consumes the most amount of power.Standby ModeThis mode is predominantly used in Desktop memory solutions where the DDR supply is desired to be ACPI compliant (Advanced Configuration and Power Interface). When this mode is activated by pulling the STBY pin low, V TT is put in High Z state, I OUT = 0 A, and V REF stays active. This is the S3 state Suspend-To-Ram or Self Refresh mode and it is the lowest DRAM power state. In this mode, the DRAM will preserve the data. While in this mode, the 34712 consumes less power than in the normal mode, because the buck converter and most of the internal blocks are disabled.Shutdown ModeIn this mode, activated by pulling the SD pin low, the chip is in a shutdown state and the outputs are all disabled and discharged. This is the S4/S5 power state or Suspend-To-Disk state, where the DRAM will loose all of its data content (no power supplied to the DRAM). The reason to discharge the V TT and V REF lines is to ensure upon exiting, the Shutdown Mode that V TT and V REF are lower than V DDQ, otherwise V TT can remain floating high, and be higher than V DDQ upon powering up. In this mode, the 34712 consumes the least amount of power since almost all of the internal blocks are disabled.START-UP SEQUENCEWhen power is first applied, the 34712 checks the status of the SD and STBY pins. If the device is in a shutdown mode, no block will power up and the output will not attempt to ramp. If the device is in a standby mode, only the V DDI internal supply voltage and the bias currents are established and no further activities will occur. Once the SD and STBY pins are released to enable the device, the internal V DDI POR signal is also released. The rest of the internal blocks will be enabled。
