ISL68134-31P-EV1Z
Evaluation Board Quick Start User Guide
Description
The ISL68134-31P-EV1Z evaluation board provides users a
method of evaluating the
ISL68134
Included on the board is a high-performance transient load
generator capable of replicating the type of high di/dt loads
typical of today's high current ASICs.
The ISL68134 is combined with the ISL99227 Smart Power
Stage (SPS) to provide a highly efficient power solution
capable of delivering up to 135A.
While the user may opt to evaluate the solution based on the
Intersil default configuration, custom configurations are easily
created using PowerNavigator™.
