DC2543A - LTC7820EUFD Demo Board | 2:1 Step-Down Charge Pump, 36V ≤ VIN ≤ 60V, VOUT = 0.5VIN @ Up to 20A

Demonstration circuit 2543A is a high efficiency, high density, open loop charge pump (inductorless) DC/DC converter. This demo board is a voltage divider which achieves a 2:1 step-down ratio from an input voltage from 36V to 60V. The output voltage is a fixed ratio of half of the input voltage (VIN/2) and can supply a 10A load current. This demo board has the option to deliver a 20A maximum load with the addition of 15 chip capacitors. See Figures 8 and 10 for the details.
