4.1 EVM Connections

Referencing the EVM connections described in Table 4-1, use the recommended test setup in Figure 4-1 to evaluate the TPSM63606(S). Working at an ESD-protected workstation, make sure that any wrist straps, bootstraps, or mats are connected and referencing the user to earth ground before power is applied to the EVM.

LABELDESCRIPTION
VIN+Positive input power connection
VIN–Negative input power connection
VOUT+Positive output power connection
VOUT–Negative output power connection

Table 4-2 EVM Signal Connections
LABEL(1) DESCRIPTION
VIN S+ Positive input sense terminal. Connect the multimeter positive lead for measuring efficiency.
VIN S– Negative input sense terminal. Connect a multimeter negative lead for measuring efficiency.
VOUT S+ Positive output sense terminal. Connect a multimeter positive lead for measuring efficiency and line and load regulation.
VOUT S– Negative output sense terminal. Connect the multimeter negative lead for measuring efficiency and line and load regulation.
PGND Ground reference point
EN Precision enable input and input voltage UVLO protection. Tie EN to GND to disable the regulator. Use a logic signal to control EN for remote ON/OFF functionality. Leave EN open for UVLO turn-on thresholds set at 5.1 V.
SYNC Synchronization input. Connect a valid clock signal to synchronize the switching frequency from 200 kHz to 2.2 MHz.
PGOOD Power-good monitor output. This is an open-drain flag with a 49.9-kΩ pullup resistor to VOUT.
BODE, VOUT Bode plot measurement and signal injection. A 10-Ω resistor from BODE to VOUT facilitates oscillator signal injection for bode plot measurement. Remove the jumper and apply a swept-frequency signal bettwen BODE and VOUT while measuring the respective response at each terminal for loop gain measurement.
