2.1.2 Source Power

To fully test the LM5113 evaluation board, a DC power supply capable of 60V and 8A is required. The power supply and cabling must present low impedance to the evaluation board. Insufficient cabling or a high impedance power supply droop during power supply application with the evaluation board inrush current. If large enough, then this droop causes a chattering condition upon power up. This chattering condition is an interaction with the evaluation board under voltage lockout, the cabling impedance and the inrush current.
