SLVUC93 September 2021 TPSM63606
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.

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. |
