Package data sheet (SLVS763 )

This section describes the jumpers and connectors on the EVM as well as how to properly connect, set

up, and use the TPS622X0EVM-229.

This is the positive input supply voltage to converter number one. Twist the leads to the input supply and

keep them as short as possible to minimize EMI transmission.

This is the return connection for the input power supply of the converter.

This is the positive connection from the output of converter number one. Connect this pin to the positive

input of the load.

This is the return connection for the output of converter number one.

This jumper enables or disables the converter. Connecting the shorting jumper between pins 1 and 2 (VIN

and EN) enables converter 1. Connecting the shorting jumper between pins 2 and 3 (EN and GND)

disables converter 1.

This jumper sets the mode of the TPS622x0. Connect the shorting jumper between pins 1 and 2 (VIN and

MODE) forces the TPS622x0 into fixed frequency PWM mode. Connecting the shorting jumper between

pins 2 and 3 (MODE and GND) enables the Power Save Mode with automatic transition from PFM mode

to fixed frequency PWM mode. Never leave this pin floating.

This is the positive input supply voltage to converter number 2. Twist the leads to the input supply and

keep them as short as possible to minimize EMI transmission.

This is the return connection for the input power supply of the converter.

This is the positive connection from the output of converter. Connect this pin to the positive input of the

load.
