SLVUCF1A September 2022 – October 2022 TPSM63610

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 TPSM63610. 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 2-1 EVM Power Connections

LABEL	DESCRIPTION
VIN+	Positive input power connection
VIN–	Negative input power connection
VOUT+	Positive output power connection
VOUT–	Negative output power connection

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/OFF functionality. Leave EN open for UVLO turn-on thresholds set at 6 V.
MODE	Mode select and synchronization input. For synchronization, connect a valid clock signal to synchronize the switching frequency from 200 kHz to 2.2 MHz. Connect MODE to VCC for FPWM mode. Connect MODE to GND for AUTO mode.
PG	Power-good monitor output. PG is an open-drain flag with a 100-kΩ pullup resistor to VOUT.
SPSP	Spread spectrum control. Connect SPSP to GND to disable spread spectrum. Connect SPSP to VCC to enable spread spectrum. Leave SPSP floating to enable spread spectrum with ripple cancellation. Power cycle the device when changing the spread spectrum configuration.
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.
