Renesas RTKA211630DE0000BU

Overview

RTKA211630DE0000BU from Renesas Electronics is an evaluation board designed to demonstrate and validate the RAA211630 QFN-packaged 60V-input, 3A synchronous step-down DC/DC regulator. It delivers a fixed 3.3V output, supports 4.5–60V input, integrates high- and low-side MOSFETs (115mΩ/40mΩ), and enables rapid prototyping of industrial and automotive power supply designs.

For engineers reviewing the RTKA211630DE0000BU datasheet, RTKA211630DE0000BU pinout, RTKA211630DE0000BU application, or RTKA211630DE0000BU equivalent, this board provides verified reference schematics, layout files, BOM, and performance waveforms for RAA211630-based buck converter implementations under real load and line conditions.

Technical Context

The RTKA211630DE0000BU implements the RAA211630 IC in a fully assembled, tested configuration with fixed 3.3V output set by R9 (62kΩ) and R10 (20kΩ), per the internal 0.8V feedback reference. Input filtering uses dual 4.7µF/100V X7R capacitors (C2, C3) and a 47µF aluminum electrolytic (C1, DNP).

Power stage components include Wurth 74439346068 (6.8µH, 6.5A) inductor, Murata GRM32ER71C226KE18L (22µF/16V) output capacitors (C8–C10), and TDK C1608X7R1C105K (1µF/16V) VCC bypass (C7). The board supports jumper-based EN activation (JP1) and provides test points (TP1–TP4) for phase node, VOUT, and enable monitoring.

FAQ

What is the primary function of the RTKA211630DE0000BU evaluation board?

The RTKA211630DE0000BU evaluation board is a fully assembled hardware platform designed to evaluate the RAA211630GNP synchronous buck regulator. It enables engineers to verify electrical performance-including efficiency, load regulation, ripple, and startup behavior-under real-world 4.5–60V input conditions while delivering a stable 3.3V/3A output. The RTKA211630DE0000BU includes reference layout, BOM, and test points for rapid validation.

Does the RTKA211630DE0000BU support adjustable output voltage?

Yes, the RTKA211630DE0000BU supports adjustable output voltage via external resistor divider on the FB pin. By default, it is configured for 3.3V using R9=62kΩ and R10=20kΩ, but users can recalculate and replace these resistors per Equation 1 in the manual to achieve other outputs based on the RAA211630's 0.8V internal reference. The RTKA211630DE0000BU schematic and BOM document this flexibility.

Which IC does the RTKA211630DE0000BU evaluate, and what package does it use?

The RTKA211630DE0000BU evaluates the RAA211630GNP - a 20-pin QFN-packaged synchronous step-down regulator. This device integrates high-side (115mΩ) and low-side (40mΩ) MOSFETs and operates across 4.5–60V input. The RTKA211630DE0000BU mounts the RAA211630GNP in its native QFN footprint, preserving thermal and electrical characteristics for accurate evaluation.

Can the RTKA211630DE0000BU be used for automotive applications?

Yes, the RTKA211630DE0000BU supports automotive-grade validation due to its evaluation of the RAA211630 - a regulator qualified for operation across –40°C to +125°C junction temperature and rated for 60V input, suitable for 12V/24V/48V vehicle subsystems. The board's layout, component selection (e.g., 100V-rated input caps), and hiccup-mode short-circuit protection (Figure 16) align with automotive reliability requirements. The RTKA211630DE0000BU serves as a starting point for such designs.
