LT3845EFE Demo Board 20V < Vin < 55V, Vout: 12V/6.25A
The is a Demonstration Board for LT3845 a high voltage synchronous current-mode DC/DC Step-down Converter with 100 to 500kHz programmable frequency. The operating frequency can be synchronized up to 600kHz. The device is designed for 12V at 6.25A 75W output from a 20 to 55V input. A soft-start feature controls the output voltage slew rate at start-up, reducing current surges and voltage overshoots. The modes of operation burst mode, discontinuous current mode and continuous current mode are jumper selectable. Both burst mode and discontinuous current mode increase the efficiency at light loads. Continuous current mode will maintain a constant switching frequency regardless of the load current.
