DC1580A - LTC3856EUH Demo Board | 4.5V ≤ VIN ≤ 14V, VOUT = 1.5V @ 50A

Demonstration circuit 1580A is a high efficiency, polyphase, synchronous buck converter with a 4.5V to 14V input range. It can supply 50A maximum load current at 1.5V output. The demo board uses the LTC®3856EUH controller. The LTC3856 is a feature-rich single-output dual-phase synchronous buck controller with on-chip drivers and remote differential output voltage sensing. This board is setup with sense resistor configuration with optional inductor DCR sensing circuit.
