DC549A - LT3431EFE Demo Board | 60V Transients, 7.5V ≤ VIN ≤ 20V, Vout = 5V @ 2A

Demonstration circuit 549 is a monolithic step-down DC/DC switching converter using the LT3431. The board is optimized for 5V output at up to 2A load current for a steady state input voltage range of 7.5V to 20V. The LT3431 is capable of withstanding input transients to 60V and runs at 500kHz with steady state input voltages that require duty cycles between 25% and 75%.
