Product details
Overview
RTKA211412DE0000BU from Renesas Electronics is an evaluation board designed to demonstrate and rapidly assess the RAA211412 630 kHz synchronous buck DC/DC regulator, supporting 5.8V–45V input, delivering up to 1A continuous output at default 3.3V, with adjustable feedback network and integrated high-side MOSFET.
For engineers reviewing the RTKA211412DE0000BU datasheet, RTKA211412DE0000BU setup, RTKA211412DE0000BU application, or RTKA211412DE0000BU reference design, this board provides validated layout, test points (J2/J3), UVLO configuration support, and component selection guidance for industrial power supply validation and embedded system integration.
Technical Context
The RTKA211412DE0000BU implements a complete peak-current-mode buck converter using the RAA211412 IC, with VIN routed to T1/T2, EN configurable via jumper J1 or external supply, and SW/VOUT accessible at test points J3/J2. It includes Wurth 744778610 (10 µH) inductor, Diodes B360B Schottky diode, and Murata GRM21BR61A476ME15L (47 µF) output capacitor.
Output voltage is set by RFB1 (62 kΩ) and RFB2 (20 kΩ) per Equation 1; input UVLO threshold is programmable via RIN1/RIN2 divider on TP1/TP2; layout follows Renesas-recommended guidelines for thermal and EMI performance, with dedicated ground planes and minimized high-di/dt loop area.

FAQ
What is the primary purpose of the RTKA211412DE0000BU evaluation board?
The RTKA211412DE0000BU evaluation board is a ready-to-use hardware platform for evaluating the RAA211412 synchronous buck regulator. It enables rapid validation of electrical performance-including load regulation, transient response, and efficiency-under real-world input conditions (5.8V–45V), and serves as a layout reference for production designs using the RTKA211412DE0000BU's target IC.
Can the output voltage of the RTKA211412DE0000BU be changed from the default 3.3V?
Yes, the RTKA211412DE0000BU output voltage is adjustable via the feedback resistor network (RFB1 and RFB2). The default 3.3V uses 62 kΩ and 20 kΩ values; other voltages (e.g., 0.8V, 5V, 12V) require recalculating RFB1 per Equation 1 and selecting appropriate inductor/capacitor values from Table 1 in the manual. No PCB modification is needed beyond resistor replacement.
Does the RTKA211412DE0000BU support input undervoltage lockout (UVLO) configuration?
Yes, the RTKA211412DE0000BU supports programmable UVLO using external resistors RIN1 and RIN2 connected between VIN and EN pins. Thresholds are calculated per Equations 2 and 3 in the manual, allowing users to set turn-on (VINR) and turn-off (VINF) levels independently-critical for battery-powered systems with variable input profiles.
What test equipment is required to operate the RTKA211412DE0000BU?
A DC power supply (5.8V–45V, ≥1A), DC electronic load (or high-wattage resistor), and oscilloscope are essential. The RTKA211412DE0000BU provides convenient access points: J2 for VOUT, J3 for SW node, TP1 for EN, and TP2 for GND. An optional second supply may drive EN separately; jumper J1 ties EN to VIN for simplified operation.
Is the RTKA211412DE0000BU compatible with other Renesas buck regulators?
No-the RTKA211412DE0000BU is specifically designed for the RAA211412 IC and is not mechanically or electrically compatible with other Renesas buck regulators (e.g., RAA211411 or RAA211413). Component values, layout, and feedback network are optimized for the RAA211412's 630 kHz switching frequency, 1A rating, and internal MOSFET characteristics.
