The TL1963EVM-384 helps designers evaluate the operation and performance of the TL1963A-xx dc/dc
converter. This converter is a 1.5-A low-noise fast-transient-response regulator.

package data sheet (

)

This section describes the jumpers and connectors on the EVM and how to properly connect, set up, and
use the TL1963EVM-384.

This is the positive input supply voltage. 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. Connect this pin to the positive input of the load.

This is the return connection for the output.

This jumper enables or disables the regulator. Connecting the shorting jumper between pins 1 and 2 (VIN
and EN) enables the converter. Connecting the shorting jumper between pins 2 and 3 (EN and GND)
disables the converter. Do not leave this pin floating.

This jumper sets the mode of the TL1963A-xx. Connecting the shorting jumper between pins 1 and 2
forces the TL1963A-xx into fixed-output mode. Use this setting with fixed-output devices only. Remove J8
shorting jumper for adjustable-output devices.

For adjustable-output devices, the output voltage may be selected using these equations:

OUT

= 1.21 (1 + R2 / R1) + I

ADJ

= 1.21 / R1

R1 < 4.17 k
