Product details
Overview
RTKA2108702H00000BU from Renesas is an evaluation board for the RAA210870 70A digital PMBus-compliant DC/DC power module, configured by default for VOUT = 0.93V, fSW = 320kHz, VIN = 4.5–12V, and continuous 70A output. It integrates pin-strap configuration support, PMBus interface via ZLUSBEVAL3Z dongle, and on-board transient load test circuitry for power integrity validation in high-current industrial and embedded power systems.
For engineers reviewing the RTKA2108702H00000BU datasheet, RTKA2108702H00000BU pinout, RTKA2108702H00000BU application, or RTKA2108702H00000BU equivalent, this page delivers verified board-level specifications, thermal layout guidance, interleave synchronization setup, Bode plot measurement methodology, and transient response characterization using the built-in MOSFET-based load step generator.
Technical Context
The RTKA2108702H00000BU implements full functional evaluation of the RAA210870 module's ChargeMode™ control architecture, supporting both pin-strap (resistor-programmed) and PMBus-configurable operation. It enables real-time monitoring of VIN, VOUT, IOUT, temperature, duty cycle, switching frequency, and fault status via PowerNavigator™ software.
Board-level features include dual-phase synchronous buck topology with remote sensing (VSENP/VSENN), external clock synchronization (SYNC input), interleave phase offset programming via SMBus address selection, and on-board bode plot loop analysis capability using a 20Ω injection resistor and network analyzer interface.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Board Size | 4.7″ × 4.8″, 8-layer FR4 with 2 oz. copper on all layers for low-impedance power delivery and thermal management. |
| Default Output | VOUT = 0.93V, fSW = 320kHz, IMAX = 70A - factory-configured pin-strap settings for immediate evaluation without PMBus. |
| Input Range | VIN = 4.5V to 12V - supports wide industrial input; <5V operation requires VCC tie to separate 5V supply or VIN. |
| Output Adjustability | VOUT programmable from 0.6V to 2.5V via RVSET_CRS/RVSET_FINE resistors; VOUT_MAX defaults to 110% of set value. |
| Transient Load Test | Integrated 100A N-channel MOSFET (BSC010NE2LSI) and 10mΩ sense resistor (R54) for controlled load-step generation up to 70A. |
| Communication Interface | PMBus-compliant via ZLUSBEVAL3Z USB dongle; also supports standalone pin-strap mode with no host required. |
| Thermal Capability | Delivers 70A at room temperature without airflow or heatsink; derating required above ambient or at higher VOUT. |

FAQ
What is the primary function of the RTKA2108702H00000BU evaluation board?
The RTKA2108702H00000BU evaluation board is a complete hardware platform for evaluating the RAA210870 70A digital PMBus power module. It provides pin-strap configuration, PMBus communication via ZLUSBEVAL3Z, remote sensing, interleave synchronization, and on-board transient load testing - enabling full characterization of efficiency, stability, transient response, and fault behavior without custom PCB design.
Does the RTKA2108702H00000BU require external hardware to operate in basic mode?
No - the RTKA2108702H00000BU operates in pin-strap mode by default (VOUT = 0.93V, fSW = 320kHz) and requires only a DC input supply (4.5–12V), electronic load, and optional DMM/oscilloscope. The ZLUSBEVAL3Z adapter and PowerNavigator™ software are optional and needed only for PMBus-based configuration, monitoring, or interleave setup.
How is output voltage adjusted on the RTKA2108702H00000BU?
Output voltage on the RTKA2108702H00000BU is adjusted by populating standard 1% 0603 resistors at RVSET_CRS (coarse adjustment) and RVSET_FINE (fine adjustment) locations on the bottom layer. Default VOUT = 0.93V uses a 21.5kΩ resistor at RVSET_CRS; values for other voltages are specified in the RAA210870 datasheet's "Output Voltage Selection" table.
Can the RTKA2108702H00000BU be used for stability analysis?
Yes - the RTKA2108702H00000BU supports bode plot measurement via a dedicated feedback loop break point (R11 removal) and 20Ω injection resistor location. When used with a network analyzer, it enables direct measurement of gain margin, phase margin, and crossover frequency - critical for validating loop stability under varying load, input, and ASCR gain/residual configurations.
What is the purpose of the SYNC test point on the RTKA2108702H00000BU?
The SYNC test point allows the RTKA2108702H00000BU to synchronize its switching frequency to an external clock source (e.g., function generator), enabling EMI reduction through frequency alignment and multi-module interleave operation. The external clock must be stable and active before enabling the module; loss of sync triggers a dedicated fault condition.
