Product details
Overview
RTKA211250DE0000BU from Renesas Electronics is an evaluation board designed to demonstrate and validate the RAA211250GNP#HA0 - a 5A synchronous buck DC/DC regulator in QFN-20 package with 4.5V–30V input, 3.3V fixed output, and integrated 70mΩ/30mΩ MOSFETs. It supports full-load testing, efficiency measurement, and layout reference for industrial power supply designs.
For engineers reviewing the RTKA211250DE0000BU datasheet, RTKA211250DE0000BU pinout, RTKA211250DE0000BU application, or RTKA211250DE0000BU equivalent, this board enables rapid validation of RAA211250-based power stages under real-world load, ripple, and thermal conditions - especially where programmable frequency, tight line/load regulation, and compact QFN integration are required.
Technical Context
The RTKA211250DE0000BU implements the RAA211250GNP#HA0 in a fully populated, production-ready layout with 3×47µF output capacitance, 3.3µH power inductor (Wurth 74439344033), and precision feedback resistors (R9 = 62kΩ, R10 = 20kΩ) setting VOUT to 3.3V per internal 0.8V reference. Input voltage is applied via screw terminals T1/T2; output is accessible at T3/T4.
It features dedicated test points (TP1–TP4) for VIN, SW, FB, and VOUT monitoring; JP1 enables EN tie-high; and J1/J2 provide access to phase node and enable signals. The board operates across the full 4.5V–30V input range and delivers up to 5A continuous output current with documented efficiency curves (e.g., >92% at 24VIN/3.3VOUT/3A).

FAQ
What is the primary function of the RTKA211250DE0000BU?
The RTKA211250DE0000BU is a dedicated evaluation board for the RAA211250GNP#HA0 synchronous buck regulator. Its purpose is to enable functional validation, performance characterization (efficiency, ripple, transient response), and PCB layout reference for designs using that IC. It is not a standalone power module but a test platform - all circuitry on RTKA211250DE0000BU directly supports evaluation of the RAA211250's capabilities under real operating conditions.
Does the RTKA211250DE0000BU support adjustable output voltage?
Yes - the RTKA211250DE0000BU ships with R9 = 62kΩ and R10 = 20kΩ to set VOUT = 3.3V, but the feedback divider is accessible and reworkable. Equation 1 in the manual (VOUT = 0.8V × (1 + R9/R10)) confirms full adjustability across the RAA211250's supported range (0.8V to VIN − 1.5V). Users can replace R9/R10 to target other outputs like 1.2V, 1.8V, or 5V, provided stability and compensation are verified.
What input voltage range is validated on the RTKA211250DE0000BU?
The RTKA211250DE0000BU is validated across 4.5V to 30V input, matching the RAA211250GNP#HA0's rated range. Performance graphs (Figures 9–16) explicitly show data at 5V, 12V, and 24V inputs - confirming operation from low-voltage industrial rails up to 28V nominal systems. The board uses screw terminals T1/T2 rated for 30V, and all input capacitors (C1–C5) meet or exceed 30V rating requirements.
Can the RTKA211250DE0000BU be used for thermal testing?
Yes - the RTKA211250DE0000BU features a thermally optimized 4-layer PCB with exposed copper pads under the RAA211250GNP#HA0 QFN-20 package and thermal vias to inner ground planes. The manual includes thermal images and efficiency-vs-load plots up to 5A, and the board's layout follows Renesas' recommended guidelines for heat dissipation. Test points TP1–TP4 allow simultaneous voltage, current, and temperature monitoring during sustained load tests.
Is the RTKA211250DE0000BU RoHS-compliant and lead-free?
Yes - the RTKA211250DE0000BU is fully RoHS-compliant and lead-free. All components listed in the Bill of Materials (Page 6) carry ROHS designators, including Murata, TDK, Wurth, and Panasonic parts. The RAA211250GNP#HA0 IC itself is marked "#HA0", denoting Renesas' standard halogen-free, lead-free QFN packaging. The board conforms to JEDEC J-STD-020 moisture sensitivity level (MSL) requirements for QFN assembly.
