Demonstration circuit 1450A is a small foot print, high efficiency synchronous buck converter with 4.5V to 26V input range. It can supply 5A maximum load current at 2.5V output. The demo board features the LTC®3854EDDB controller. The controller features a 400kHz constant frequency current mode architecture and allows RSENSE or DCR inductor current sensing. The demo board is configured using RSENSE.
