2.1.1 EVM Connections

Referencing the EVM connections described in Table 2-1, the recommended test setup to evaluate the TPS543521 is shown in Figure 2-1. Working at an ESD-protected workstation, make sure that any wrist straps, boot straps, or mats are connected and referencing the user to earth ground before handling the EVM.

LABELDESCRIPTION
VIN (J1)Positive input voltage to the converter
GND (J1)Negative input voltage to the converter
VOUT (J2)Positive output voltage of the converter
GND (J2)Negative output voltage of the converter

LABELDESCRIPTION
VIN_sen(TP1)Measure input voltage
VOUT_sen(TP3)Measure output voltage
GND(TP9)Ground of the converter
SS/PG (TP7)Soft-start function or Power-Good function depending on the mode selection
BODE(TP5)Injection point for loop response
EN (TP8)EN indicator of converter
SYNC (TP6)SYNC clock injection
Header (J3 and J4)

Leaving J3 and J4 open enables the converter.

Connect (PIN-1 to PIN-2) of J3 and (PIN-1 to PIN-2) of J4 can set system UVLO voltage with an external resistor divider R1 and R2.

Connect (PIN-1 to PIN-2) of J3 and (PIN-2 to PIN-3) of J4 can disable the converter.

Header (J5)When Power-Good mode is selected, connecting (PIN-1 to PIN-2) of J5 for the PG pin connected to pullup voltage.
