Renesas RTKA808013DE0000BU

Overview

RTKA808013DE0000BU from Renesas Electronics is a 3A synchronous buck regulator evaluation board featuring a fixed 1.2V output, 2.7V–5.5V input range, 1.5MHz switching frequency, and TSOT23-6 packaged RAA808013 IC - designed for compact, high-efficiency DC/DC conversion in space-constrained portable and embedded power systems.

For engineers reviewing the RTKA808013DE0000BU datasheet, RTKA808013DE0000BU pinout, RTKA808013DE0000BU application, or RTKA808013DE0000BU equivalent, this evaluation board enables rapid validation of load transient response, efficiency across temperature, soft-start behavior, hiccup-mode OCP, and EN-controlled sequencing under real-world 3A load conditions.

Technical Context

The RTKA808013DE0000BU implements a monolithic synchronous buck topology using integrated 77mΩ high-side and 42mΩ low-side MOSFETs, supporting 100% duty cycle operation in dropout. It operates at a fixed 1.5MHz switching frequency to minimize external passive size while maintaining stable regulation across ±0.5% load regulation at 25°C.

Control features include cycle-by-cycle overcurrent protection, thermal shutdown, input UVLO (typ. 2.3V), and enable-driven power sequencing. The board's feedback network uses a precision 51kΩ/51kΩ resistor divider to set the default 1.2V output, with adjustability down to 0.6V via FB pin reconfiguration.

FAQ

What is the RTKA808013DE0000BU used for?

The RTKA808013DE0000BU is an evaluation board for the RAA808013 3A synchronous buck regulator IC. It enables engineers to validate performance metrics-including efficiency, transient response, thermal behavior, and protection functionality-under real operating conditions before integrating the RAA808013 into final designs. The RTKA808013DE0000BU is not a production component but a development tool.

Does the RTKA808013DE0000BU support adjustable output voltage?

Yes - although the RTKA808013DE0000BU is preset to 1.2V, its output voltage can be adjusted from 0.6V to 3.3V by modifying the feedback resistor divider (R1/R2) per Equation 1 in the manual. Table 1 provides exact resistor values for common output voltages, enabling quick reconfiguration for different core or I/O rail requirements on the RTKA808013DE0000BU.

What are the key protection features implemented on the RTKA808013DE0000BU?

The RTKA808013DE0000BU demonstrates built-in protections inherited from the RAA808013 IC: cycle-by-cycle overcurrent protection, short-circuit protection with hiccup mode, input undervoltage lockout (~2.3V), and over-temperature shutdown. These are validated in Figures 32–33 (hiccup under short) and thermal performance graphs across -40°C to +85°C on the RTKA808013DE0000BU.

Can the RTKA808013DE0000BU be used to evaluate load transient response?

Yes - the RTKA808013DE0000BU includes dedicated test points and layout optimized for transient measurement, with Figures 24–26 explicitly showing load-step responses (0A→3A, 1.5A→3A). Its low-inductance layout, accessible SW and PG pins, and onboard current-sense capability make the RTKA808013DE0000BU ideal for characterizing dynamic line/load regulation and control-loop stability.

Is the RTKA808013DE0000BU compatible with standard lab equipment?

Yes - the RTKA808013DE0000BU is designed for compatibility with common bench instruments: it accepts 0–6V bias supplies (≤5.5V recommended), interfaces with electronic loads up to 15A, and provides oscilloscope-accessible signals (SW, EN, PG, VOUT) via turret terminals. The Quick Start Guide (Section 1.2) confirms setup using standard DMMs and 100MHz quad-trace scopes - all verified on the RTKA808013DE0000BU.
