TPS63806EVM
2 Setup
This section describes how to properly use the TPS63806EVM.
2.1 Input/Output Connector and Header Descriptions
2.1.1 J1, Pin 1 and 2 – VIN
Positive input connection from the input supply for the EVM.
2.1.2 J1, Pin 3 and 4 – S+/S-
Input voltage sense connections. Measure the input voltage at this point.
2.1.3 J1, Pin 5 and 6 – GND
Vin GND return connection from the input supply for the EVM, common with J2, pin 5 and 6.
2.1.4 J2, Pin 1 and 2 – VOUT
Output voltage connection.
2.1.5 J2, Pin 3 and 4 – S+/S-
Vout Sense and GND Sense low-current sense lines for sampling the output voltage at the output
capacitor.
2.1.6 J2, Pin 5 and 6 – GND
Vout GND return connection for the output voltage, common with J1 pin 5 and 6.
2.1.7 J3 – PG GND
Power Good (PG) test point and GND connection.
2.1.8 JP1 – MODE
Shorting jumper between the center pin MODE and PFM enables automatic transition to power-saving
mode at light-load currents as described in the data sheet; shorting jumper between the center pin MODE
and PWM enables forced PWM mode.
2.1.9 JP2 – ENABLE
Shorting jumper between the center pin EN and ON turns on the unit. Shorting jumper between the center
pin EN and OFF turns the unit off.
2.2 Setup
To operate the EVM, connect an input supply with the positive lead to J1, pins 1 and 2 and negative lead
to J1, pins 5 and 6; connect a load with the positive lead to J2, pins 1 and 2 and the negative lead to J2,
pins 5 and 6; short EN and ON (pins 2 and 3) of JP2 with a shorting jumper.
