RTKA2108332H00000BU Eval Board

Pin-Strap Configurable 33A Step-Down PMBus-Compliant DC/DC Power Supply Module

The RAA210833 is a pin-strap configurable 33A step-down PMBus-compliant DC/DC power supply module that integrates a digital PWM controller, synchronous MOSFETs, a power inductor, and passive components. Only input and output capacitors are needed to finish the design. Because of its thermally-enhanced HDA packaging technology, the module can deliver up to 33A of continuous output current without the need for airflow or additional heat sinking. The RAA210833 simplifies configuration and control of Renesas digital power technology while offering an upgrade path to full PMBus configuration through the pin-compatible ISL8278M.

The RTKA2108332H00000BU evaluation board is a 4in x 4.5in 4-layer FR4 board with 2oz. copper in all layers. The RAA210833 comes with a preprogrammed configuration for operating in a pin-strap mode. Output voltage, switching frequency, input UVLO, soft-start/stop delay and ramp times, and the device SMBus address can be programmed with external pin-strap resistors.

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 RTKA2108332H0000BBU can operate in pin-strap mode without needing the ZLUSBEVAL3Z adapter or PMBus communication.

Key Features

  • VIN range of 4.5V to 14V, VOUT adjustable from 0.6V to 5V
  • Pin-Strap mode for standard settings: VOUT, switching frequency, input UVLO, soft-start/stop, and external synchronization
  • Real-time telemetry for VIN, VOUT, IOUT, temperature, duty cycle and switching frequency, and 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

Applications

  • Server, telecom, storage, and datacom
  • Industrial/ATE and networking equipment
  • General purpose power for ASIC, FPGA, DSP, and memory
