    C interface, which is used to adjust PMIC settings and communicate status. The I C interface can be controlled by a dedicated Renesas proprietary Graphical User Interface (GUI), which requires a host computer. The EVB includes switches and jumpers to emulate the signal interface (some of which are configurable MPIO) with a microprocessor-based system.

    RTKA215300DE0000BU Evaluation Board Manual Operating Characteristics 2.2.1 Operating Limits EVB can operate across the full ranges for voltage, current, and temperature described in the datasheet. Each regulator can be loaded to its full electrical rating but PMIC thermal ratings must be respected, so the combined load on all regulators is limited by PMIC dissipation, PCB design, and thermal environment.

Before applying load to the regulator outputs, increase the current limit on the input (VIN) supply to a level that supports VIN voltage when loads are applied. 2. Connect loads to the buck regulator outputs at the 4mm banana sockets shown in Figure 7.

    RTKA215300DE0000BU Evaluation Board Manual 2.3.6 Transient Load Circuits 2.3.6.1 Overview There are two separate transient load circuits on the EVB. The load located in the green box in Figure 11 can both draw current from regulator outputs and provide current to regulator outputs. This load is called LOAD1 in the following text.
  • Page 13 RTKA215300DE0000BU Evaluation Board Manual If the previous procedure does not produce the required transient load currents, complete the following alternative procedure. ▪ Set the input signal amplitude to about 5V (-5V to drive Q4 on). This turns the FETs on fully and their resistances are relatively low.
