Evaluation Board , RAA210925 DC/DC Converter, Step Down, 25A, PMBus, ChargeMode

Evaluation board for pin-strap configurable 25A step-down PMBus-compliant DC/DC power supply module. This evaluation board is a 4.0in x 4.5in 8-layer FR4 board with 2oz. copper on top and bottom layer and 1oz. copper in buried layers. The board comes with a placeholder for pin-strap resistors to adjust output voltage, switching frequency, input undervoltage lockout (UVLO) protection threshold, device PMBus address, overcurrent limit, ASCR setting and soft-start setting. More configurations can be easily programmed or changed using a PMBus compliant serial bus interface. The ZLUSBEVAL3Z (USB to PMBus adapter) is provided with this evaluation board which connects the evaluation board to a PC to activate the PMBus communication interface. The PMBus command set is accessed by using the PowerNavigator™ evaluation software from a PC running Microsoft Windows. The RTKA2109252H00000BU can operate in pin-strap mode without needing the ZLUSBEVAL3Z adapter or PMBus communication.

• VIN range of 4.5V to 14V, VOUT adjustable from 0.6V to 5V, up to 95.5% efficiency
• Real time telemetry for VIN, VOUT, IOUT, temperature, duty cycle, switching frequency, fault logging
• ChargeMode control that is tunable with pin-strap resistors or the PMBus interface
• Mechanical switch for enable and the power-good LED indicator
• Used at server, telecom, storages and datacom applications
• Industrial/ATE and networking equipment
• Used at general purpose power for ASIC, FPGA, DSP and memory applications
