2.1 EVM Connections

Referencing the EVM connections described in Table 2-1, use the recommended test setup in Figure 2-1 to evaluate the TLVM13610. 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.

Table 2-2 EVM Signal Connections
LABEL 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.
GND Ground reference point
SW Switch node monitor output
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 and OFF functionality. Leave EN open for UVLO turn-on thresholds set at 6 V.
PG Power-good monitor output. PG is an open-drain flag with a 100-kΩ pullup resistor to VOUT.
CHA, CHB Bode plot measurement and signal injection. A 10-Ω resistor from CHA to CHB facilitates oscillator signal injection for bode plot measurement. Remove the jumper and apply a swept-frequency signal between CHA and CHB while measuring the respective response at each terminal for loop gain measurement.
