Product details

Overview

RTKA211605DR0010BU from Renesas Electronics is a demonstration board designed to evaluate the RAA211605 450 kHz synchronous buck DC/DC regulator, supporting 4.5V–60V input, delivering 3.3V/0.5A output with adjustable feedback, and featuring integrated 600mΩ high-side MOSFET for industrial power conversion validation.

For engineers reviewing the RTKA211605DR0010BU datasheet, RTKA211605DR0010BU application, RTKA211605DR0010BU pinout, or RTKA211605DR0010BU equivalent, this board enables rapid functional verification, load/transient performance assessment, layout reference extraction, and output voltage tuning via R3/R4 resistor network modification.

Technical Context

The RTKA211605DR0010BU implements a complete, ready-to-power buck converter using the RAA211605 IC in TSOT-23-6 package, with fixed 3.3V output set by 20kΩ (R4) and 62kΩ (R3) feedback resistors, and includes all critical passive components: 33µH power inductor (Wurth 74408943330), 10µF/16V output capacitor (Murata GRM32DR71C106KA01L), and 2.2µF/100V input capacitor (Murata GRM32ER72A225KA35L).

It supports quick test setup with EN tied to VIN via 0Ω resistor (R1), provides accessible test points (TP1, TP2, T1–T4) for voltage, phase node, and current monitoring, and delivers verified performance across input range - including efficiency curves up to 90% at 0.5A and load regulation within ±20mV from 0.25A to 0.5A at 24V_IN.

Key Specifications

Parameter	Value and Actual Design Meaning
Board Type	Demonstration board for RAA211605 buck regulator - not a standalone IC or discrete component.
Input Voltage Range	4.5V to 60V - validated across full range with stable 3.3V output and no thermal shutdown under 0.5A load.
Output Voltage	3.3V nominal (adjustable via R3/R4 feedback network per Equation 1 - default values yield V_OUT = 3.3V).
Max Output Current	0.5A continuous - supported with ≤20mV load regulation shift and <10mV p-p ripple at full load (24V_IN).
Switching Frequency	450 kHz - fixed internal oscillator frequency enabling compact magnetics and predictable EMI profile.
Key Passive Components	L1 = 33µH/1.2A (Wurth 74408943330); C_OUT = 10µF/16V X7R (Murata GRM32DR71C106KA01L); C_IN = 2.2µF/100V X7R (Murata GRM32ER72A225KA35L).

FAQ

What is the primary function of the RTKA211605DR0010BU?

The RTKA211605DR0010BU is a demonstration board built around the RAA211605 synchronous buck regulator IC. Its primary function is to enable rapid functional evaluation, performance characterization (efficiency, ripple, transient response), and PCB layout reference extraction for designs using the RAA211605. It is not a production-ready power module but a validated engineering tool.

Can the output voltage of the RTKA211605DR0010BU be changed from 3.3V?

Yes, the RTKA211605DR0010BU's output voltage is adjustable via the feedback resistor network (R3 and R4). By replacing R3 (62kΩ) and/or R4 (20kΩ) per Equation 1 in the manual, users can set any output voltage ≥0.8V. The board includes solder pads and documentation for safe reconfiguration without modifying the RAA211605 IC itself.

Does the RTKA211605DR0010BU include an enable control interface?

Yes, the RTKA211605DR0010BU provides EN control: EN is tied to VIN by default through 0Ω resistor R1, but R1 and R2 (62kΩ) can be reconfigured to implement input undervoltage lockout (UVLO). This allows users to validate startup sequencing, power-good behavior, and controlled enable/disable functionality during system integration testing.

What test points are available on the RTKA211605DR0010BU for signal measurement?

The RTKA211605DR0010BU includes TP1 (white) and TP2 (black) mini test points for probing FB and SW nodes, plus four terminal blocks: T1 (VIN+), T2 (GND), T3 (VOUT+), and T4 (GND). These allow direct oscilloscope access to input/output voltages, switching node waveforms, and load current sensing - essential for validating stability, ripple, and transient response.

Is the RTKA211605DR0010BU RoHS compliant and suitable for industrial applications?

Yes, the RTKA211605DR0010BU is RoHS compliant (per Bill of Materials and manual declarations) and designed for industrial-grade evaluation. All components - including Murata capacitors, Wurth inductor, and Renesas RAA2116054GP3#JA0 IC - meet industrial temperature and reliability requirements, and the board has been characterized across 4.5V–60V input and -40°C to +125°C ambient (per RAA211605 datasheet specifications).
