The TPS541620 is a highly integrated non-isolated dual DC-DC converter that is capable of high-frequency operation in a 3-mm × 5-mm package. The device can be configured as two single 6-A rails or combined to drive a single 12-A current load. The device implements a fixed-frequency advanced current mode control (ACM) with selectable ramp amplitude configurations to optimize the loop bandwidth. Two mode selection pins (MODE1 and 2) are used to select switching frequency, configuration, clock phase delay, and internal compensation.
