概要

The RTKA2108502H00000BU evaluation board is an 8-layer FR4 board with 2oz. copper on all layers. The board measures 4. 7in x 4. 8in. The evaluation board includes placeholders for the pin-strap resistor population that allow for the adjustment of the output voltage, switching frequency, soft-start/stop timing, input UVLO, ASCR (gain and residual) parameters, and the device PMBus address. Also, fault limits can be programmed or changed easily with the PMBus compliant serial bus interface.

The evaluation board makes use of the RAA210850, a 50A step-down DC/DC power supply module with an integrated digital PWM controller, dual-phase synchronous power switches, inductors, and passives. Only input, output capacitors and minimal passives are required to finish the design. The board can output a continuous current at 50A without airflow or heat sink. The RAA210850 uses a ChargeModeTM control (ASCR) architecture that responds to a transient load within a single switching cycle.

Provided with the evaluation kit, the ZLUSBEVAL3Z (a USB to PMBus adapter) connects the evaluation board with a PC to activate the PMBus communication interface. The PMBus command set is accessed by using the PowerNavigatorTM evaluation software from a PC running Microsoft Windows.

The RTKA2108502H00000BU can operate in pin-strap mode without needing the ZLUSBEVAL3Z adapter or PMBus communication.
