Description

Demonstration circuit board DC1052 includes two separate circuits for performance evaluation of the LTC4218 Hot Swap Controller. The standard version of the Controller (LTC4218) is intended to operate with 2.9V to 26.5V rails, while the LTC4218- 12 has present threshold for 12V applications.

The circuit of DC1052A is assembled with the LTC4218CGN and LTC4218CDHC-12. Circuit breaker thresholds in both circuits are adjusted to 7.5A.

The LTC4218 features accurate current limiting with foldback and a ground-referred current monitor. The current monitor sources a current that is proportional to the sense voltage and it may be converted to a voltage signal with the appropriate resistor.

Current limit may be reduced by placing the external resistor between GND and the Iset pin.

The DC1052 design lets the LTC4218 operate through turn-on and turn-off transients as well as in the steady state mode.
