dc1640a-a DC1640A-A LTC3833EUDC Demo Board | 4.5V ≤ VIN ≤ 14V, VOUT = 1.5V @ 20A, Inductor DCR Sensing Demonstration circuit 1640A is a 1.5V/20A synchronous buck converter operating with a switching frequency of 300kHz over an input voltage range of 4.5V to 14V. The demo board comes in two versions. The A version uses inductor DCR current sensing with an iron powder inductor for high efficiency. The B version uses a 2mΩ /1% sense resistor for accurate current sensing with a low DCR ferrite inductor. The fixed on-time valley current mode topology of the LTC3833 allows for a fast load step response. DC1640A-A
