Product details
Overview
RTKA211630DE0010BU from Renesas Electronics is an evaluation board designed to demonstrate and validate the RAA211630 HTSSOP-packaged synchronous buck DC/DC regulator, supporting 4.5V–60V input, delivering 3.3V/3A output with integrated 145mΩ high-side and 45mΩ low-side MOSFETs for industrial power conversion applications.
For engineers reviewing the RTKA211630DE0010BU datasheet, RTKA211630DE0010BU pinout, RTKA211630DE0010BU application, or RTKA211630DE0010BU equivalent, this board enables rapid validation of load regulation, efficiency across wide VIN, startup sequencing with external soft-start, and layout reference for high-current 60V-input buck converters.
Technical Context
The RTKA211630DE0010BU implements a fixed 3.3V output configuration using R9 (62kΩ) and R10 (20kΩ) feedback resistors per Equation 1, targeting stable operation at up to 3A continuous load. It uses the RAA211630GSP IC in 16-pin HTSSOP package with integrated power FETs, BST capacitor, and PGND/AGND separation for noise-sensitive analog regulation.
Board-level features include jumper JP1 for VIN-to-EN shorting, test points TP1–TP4 for VOUT, phase node, EN, and PG monitoring, and a 6.8µH shielded power inductor (Wurth 74439346068) rated for 6.5A saturation current-enabling full-load evaluation under thermal and transient stress conditions.

FAQ
What is the primary function of the RTKA211630DE0010BU evaluation board?
The RTKA211630DE0010BU evaluation board is designed exclusively to evaluate the RAA211630 synchronous buck regulator IC. It provides a fully assembled, tested platform with fixed 3.3V output, enabling engineers to measure efficiency, load/line regulation, startup behavior, and thermal performance across its 4.5V–60V input range. The board includes test points, jumpers, and reference layout for immediate lab validation of the RAA211630GSP device.
Does the RTKA211630DE0010BU support adjustable output voltage?
Yes, the RTKA211630DE0010BU supports adjustable output voltage via the FB pin (U1 Pin 12). Though configured for 3.3V by default using R9 (62kΩ) and R10 (20kΩ), Equation 1 in the manual allows recalculating R9 for other outputs. Users must replace R9 accordingly while retaining R10 = 20kΩ; no hardware modification beyond resistor change is required to reconfigure VOUT.
What input voltage range can be safely applied to the RTKA211630DE0010BU?
The RTKA211630DE0010BU accepts input voltages from 4.5V to 60V DC, matching the operational range of the underlying RAA211630 IC. Input must be applied between terminals T1 (VIN) and T2 (GND); exceeding 60V may damage the RAA211630GSP IC or input capacitors. The board's C1 (47µF/100V) and C2/C3 (4.7µF/100V) are rated for this maximum, ensuring safe operation at full-rated input.
How is enable functionality implemented on the RTKA211630DE0010BU?
Enable functionality on the RTKA211630DE0010BU is implemented via jumper JP1, which shorts VIN to the EN pin (U1 Pin 2). With JP1 installed, the regulator powers on as soon as input voltage is applied. Removing JP1 allows external control of EN using a logic signal (0V–60V compatible), supporting sequenced power-up or system-level shutdown. EN threshold is internally set at ~1.2V typical.
Can the RTKA211630DE0010BU be used to evaluate hiccup-mode overcurrent protection?
Yes, the RTKA211630DE0010BU demonstrates hiccup-mode overcurrent protection as shown in Figure 16. When VOUT is shorted under full load, the RAA211630GSP enters hiccup mode-cycling ON/OFF until fault clears. This behavior is observable at TP3 (VOUT) and TP4 (phase node), confirming built-in protection without external circuitry. Recovery is automatic upon short removal, validating robustness for industrial fault conditions.
