Description
The CSD87588NEVM-603 is designed to use a regulated voltage ranging 8 to 20 V to produce 1.0-V
output at up to 25 A of load current. The CSD87588NEVM-603 demonstrates Power Block II together with
TI controller TPS51219 in a typical low voltage application with D-CAP2™ mode operation. The EVM also
provides a number of testpoints to evaluate the performance of the CSD87588N.
