Ripple and Noise Notes

Ripple and Noise is measured according to the description below in accordance with JEITA RC-9131C (Sections 7.16, 7.17 and 7.18). The measurement connection is shown in Fig. 3-1. C1 (0.1µF Ceramic Capacitor), C2 (47uF Aluminum Electrolytic Capacitor) must be connected in parallel at 30cm from the output terminals, along the load cable. Attach a maximum 1.5m 50Ω coaxial cable from the ceramic capacitor electrodes to a filter attachment installed on the oscilloscope. The filter attachment consists of C3 (4700pF film capacitor) in series with R (50Ω resistor). Use 100MHz bandwidth oscilloscope or equivalent.

In general, output ripple voltage and output spike noise voltage can be reduced by increasing external capacitance.

OPERATION MANUAL

ADDRESSING (A3, A2, A1, A0 inputs)

To communicate with the TPS3000, the master must first address the slave devices via a slave address byte. The slave address byte consists of seven address bits and a direction bit that indicates the intent to execute a read or write operation. The TPS3000 features four variable address lines that allow up to 16 Supplies to be connected on a single bus. PMBus uses 7 bit addressing. There is constant part of address and variable part of address: Constant part of address consists of 3 Most Significant Bits A6, A5, and A4 and always equals 010. Variable part of address consists of 4 Least Significant bits: A3, A2, A1, and A0. These four bits are assigned using the hardware connections of the PS address connector. The Address lines (A3, A2, A1, and A0) are internally pulled up by resistors to +5V. The address lines can be left open for ‹1› address or connected for ‹0› address. The Address Space contains these 16 possible addresses:

R/W

A6 A5 A4 A3 A2 A1 A0

0 1 0 0 0 0 0 x 40h 0 1 0 0 0 0 1 x 42h 0 1 0 0 0 1 0 x 44h 0 1 0 0 0 1 1 x 46h 0 1 0 0 1 0 0 x 48h 0 1 0 0 1 0 1 x 4Ah 0 1 0 0 1 1 0 x 4Ch 0 1 0 0 1 1 1 x 4Eh 0 1 0 1 0 0 0 x 50h 0 1 0 1 0 0 1 x 52h 0 1 0 1 0 1 0 x 54h 0 1 0 1 0 1 1 x 56h 0 1 0 1 1 0 0 x 58h 0 1 0 1 1 0 1 x 5Ah 0 1 0 1 1 1 0 x 5Ch 0 1 0 1 1 1 1 x 5Eh

In case more than one unit is connected to PMBus, each unit must be set to its own unique address. Duplicate addressing is not allowed.

Note: The TPS3000 is always considered a slave device.

SERIAL CLOCK (SCL)

This line is clocked by the Master which controls the PMBUS. It is connected to +5.0V or +3.3V (referenced to “SMB GND”) via a 5.0kΩ pull-up resistor.

Byte Hex Address

SERIAL DATA (SDA)

This is a Bi-Directional line which is connected to +5.0V or +3.3V (referenced to "SMB GND") via a 5.0kΩ pull up resistor.

ALERT

ALERT is used to indicate to the HOST about any Faults/Error/Warning Conditions. This line is connected to +5.0V or +3.3V(referenced to "SMB GND") via a 3.0kΩ pull up resistor. This Signal is HIGH to indicate that no fault/error/warning is present. If some fault/error/warning occurs, the signal will go LOW. The Host system must poll multiple supplies after receiving ALERT to retrieve fault/error/warning information.

OPERATION MODE

This command is used to set the way the user Enables/Disables the output of the Unit. Setting the Operation Mode to “Remote Mode” allows the user to control the output using the “OPERATION ON/OFF” command via the I2C. In the “Local Mode” the user has the option to use the Front Panel Output Enable Switch or the “PSON” pin on the Signals connector.

Command code

D8h R/W Byte 00h=Remote

D8h R/W Byte 80h=Local

When the user switches from “Local Mode” to “Remote Mode” for first time after applying AC power, the default Operation State will be “Operation ON”. To keep the unit OFF when switching to “Remote Mode”, the “Operation OFF” command must be sent immediately after entering “Remote Mode”. If the user tries to change Operation State before the user changes Operation Mode to “Remote Mode” the unit will respond with error and will ignore the command.

Once the user enters “Remote Mode” the Front Panel Output Enable Switch has no longer control of the Output until the user changes over to “Local Mode”.

Attention: If the unit is ON and the user issues “Operation OFF” follow by “Operation ON” command within 3.0 Sec, the Unit will remain in the OFF state for 3.0 Sec from the time the user issue the “Operation OFF” command. Also in Local Mode the Front Panel Output Enable Switch will behave in the same way. If the unit was enabled and the User disable it follow by Enable within 3.0 Sec, the Unit will remain in the OFF state for 3.0 Sec from the time the user disabled the unit.

MONITORING THE OUTPUT VOLTAGE (READ_VOUT)

The accuracy of the voltage reading is +/-2% The output voltage is read before the ORING Circuit (~50mV Voltage drop @ load, no drop @no load). The read back Output Voltage can be calculated using the “Direct data Format”. Refer to Table 1 for the Coefficients for calculating the Output Voltage.

Command code

8Bh Read Word 2

Example:

Hex read back = 02FF h. Converted to Decimal = 767. Using the required coefficients the Output Voltage (767*10 Add 0.05V to compensate ORing Circuit drop. So, the actual voltage is (Ex: 22.50 + 0.05 = 22.55V). Read the Actual Output Voltage on the Output Bus Bar (Ex: 22.88V).

MONITORING THE OUTPUT CURRENT (READ_IOUT)

The accuracy of the current reading is +/-10% The read back output current can be calculated using the “Direct data Format”. Refer to Table 1 for the Coefficients for calculating the Output Current.
