Power
The TLK6002EVM can be operated off of a single 5-V power supply using the onboard linear dropout
voltage regulators to generate the voltages required to correctly operate the TLK6002, 1-V, 1.5-V, and
1.8-V power rails. Additional 1.2-V, 2.5-V, and 3.3-V supplies have been added to support additional
circuitry on the EVM board and to provide voltage to the peripheral ports to minimize the amount of power
circuitry needed on those boards. Banana jacks and selection headers allow external laboratory power
supplies to be used instead of the onboard LDO regulators. The LDO regulators used on the EVM are TI’s
TPS74401 (or TPS74201 depending on available stock at the PCB assembly shop) and are adjustable
using a resistor divider between the output and a feedback pin. Each regulator has been set to provide the
appropriate minimum, nominal, or maximum voltage per the data sheet limits at its output when
appropriately set. However, no sense lines are connected to the plane near the DUT to compensate for
resistive loss through the board. This loss must be less than 5 mV to 10 mV and not affect the operation
of the TLK6002 device. If more information on the use of these regulators is desired, consult the regulator
data sheets found at
www.ti.com
.
To modify your power supply configuration between either all individual supplies, all onboard regulators, or
a combination of both, simply change the jumper position on the appropriate power supply headers
(JMP58, JMP63, JMP70, JMP85, JMP89, and JMP149) selecting either the BANANA JACK or the REG
pin in combination with the center pin. The following figure shows how to use the onboard regulators for
the 1.2-V, 1.5-V, 1.8-V, 2.5-V, and 3.3-V supply rails, and an individual power supply connected to the 1-V
banana jack (P16) and 2.5-V banana jack (P29). The 5-V power supply is required for operation of the
LEDs on this board even if you are not using the onboard voltage regulators and can be provided from a
laboratory power supply through the banana jack (P1) or through the supplied 5-Vdc transformer. Moving
the jumper location on JMP81 changes the 5-V power supply source from the banana jack or supplied
5-Vdc transformer.
