Full-Featured –48-V Hot Swap Power Manager
2.3 Full-Featured –48-V Hot Swap EVM Operating Specifications
The full-featured –48-V hot swap EVM is intended to allow some degree of user reconfiguration. This allows
designers to set up the circuit to better represent the characteristics of their target application. Potential
modifications include changing the inrush limiting, the fault timing, and load characteristics. However, under no
circumstances should the EVM kit be operated beyond the absolute maximum conditions specified in Table 2.
