DC1530A - LTC3829EUHF Demo Board | 3-Phase Buck, 7V ≤ VIN ≤ 14V, Vout = 1.5V @ 60A

Demonstration circuit 1530A is a high efficiency, 3-phase, synchronous buck converter with a 7V to 14V input range. It can supply 1.5V @ 60A maximum load current. The demo board uses the LTC®3829EUHF controller. The LTC3829 is a feature-rich, single output, 3-phase synchronous buck controller with on-chip drivers, remote output voltage sensing, inductor DCR temperature compensation, phase shedding, nonlinear control and adaptive voltage positioning (AVP). It is suitable for inputs from 4.5V to 38V and outputs up to 5V.
