Product details
Overview
RTKA489800DE0000BU from Renesas Electronics is an evaluation board for the RAA489800 bidirectional buck-boost voltage regulator IC. It supports forward and reverse power conversion up to 21V, features SMBus/I²C programmability, and includes on-board LEDs for forward/reverse power-good and fault status indication. Designed for battery and optical system evaluation, it enables rapid validation of bidirectional regulation in USB PD, adapter-to-system, and system-to-adapter configurations.
For engineers reviewing the RTKA489800DE0000BU datasheet, RTKA489800DE0000BU pinout, RTKA489800DE0000BU application, or RTKA489800DE0000BU equivalent, this board provides full access to RAA489800 configuration registers (e.g., ForwardRegulatingVoltage at 0x15H, ReverseRegulatingVoltage at 0x49H), real-time protection monitoring (OCP/OVP/UVP/OTP), and mode control via FRWEN/RVSEN pins - critical for embedded power architecture development.
Technical Context
The RTKA489800DE0000BU implements the RAA489800 controller in a fully assembled 4-switch buck-boost topology with optional 2-switch buck mode. It supports input voltage ranges from 3.8V to 23V on both ADP and system sides, delivers regulated output up to 21V, and operates at switching frequencies up to 1 MHz with Renesas R3™ Technology for high light-load efficiency and seamless DCM/CCM transitions.
It integrates dual current-sensing paths (CSIP/CSIN for ADP side; CSOP/VOUTS for system side), programmable soft-start via REF pin capacitor, and SMBus-address configuration through ADDR0/ADDR1 pins. Protection functions include absolute overvoltage protection, input/output internal discharge, and active switching for negative voltage transitions - all accessible and testable on the board.

FAQ
What is the primary function of the RTKA489800DE0000BU?
The RTKA489800DE0000BU is an evaluation board for the RAA489800 bidirectional buck-boost regulator IC. It enables hardware validation of forward (adapter-to-system) and reverse (system-to-adapter) power conversion, including programmable voltage regulation, SMBus-controlled protection thresholds, and real-time mode transition analysis - all using the actual RAA489800ARGNP#AA0 IC mounted on the board.
Does the RTKA489800DE0000BU support both 4-switch and 2-switch buck operation?
Yes, the RTKA489800DE0000BU supports both configurations. Jumper settings (JP4, JP6, JP7) and resistor options (e.g., R109, R11, C36) allow reconfiguration between full 4-switch buck-boost and 2-switch buck mode. The board schematic and layout guidelines explicitly document routing and component placement for both topologies, enabling direct comparison of efficiency, thermal behavior, and transient response.
How is output voltage programmed on the RTKA489800DE0000BU?
Output voltage on the RTKA489800DE0000BU is programmable in two ways: (1) via PROG pin resistor (e.g., R23) for default forward output voltage, per RAA489800 datasheet tables; and (2) dynamically via SMBus registers - ForwardRegulatingVoltage (0x15H) for forward mode and ReverseRegulatingVoltage (0x49H) for reverse mode - both accessible through the included GUI and USB interface.
What protection features are implemented and testable on the RTKA489800DE0000BU?
The RTKA489800DE0000BU implements and exposes all RAA489800 protections: overcurrent (OCP), overvoltage (OVP), undervoltage (UVP), and overtemperature (OTP), plus absolute overvoltage protection and internal discharge control. These are actively monitored and indicated via LED1 (ALERT#), LED2 (FRWPG), and LED3 (RVSPG), and their thresholds are configurable via SMBus registers 0x3FH, 0x4AH, 0x4BH, and 0x14H.
Can the RTKA489800DE0000BU be used to evaluate SMBus address conflict resolution?
Yes. The RTKA489800DE0000BU includes ADDR0 and ADDR1 pins with onboard jumpers (SW3, SW4) to configure the RAA489800's SMBus address across multiple values (e.g., 0x96H default). This allows engineers to verify multi-device SMBus bus sharing, address arbitration, and register-level communication integrity - essential for systems integrating multiple RAA489800 regulators or mixed Renesas PMICs.
