Supply Renesas Evaluation Boards, Mingjiada Electronics Supply Synchronous Buck Controller Evaluation Boards

Shenzhen Mingjiada Electronics Co., Ltd. — Long-term commitment to providing Renesas synchronous buck controller evaluation boards, designed to assist engineers in accurately measuring key metrics such as efficiency, ripple, and transient response.

Mingjiada Electronics consistently supplies multiple Renesas synchronous buck controller evaluation boards, covering extensive requirements from traditional buck to cutting-edge three-stage buck topologies:
I. Traditional High-Performance Synchronous Buck Evaluation Boards
These evaluation boards are based on Renesas' mature high-performance controllers, renowned for high precision and reliability, and widely applied in industrial, communications, and computing sectors.
1. ISL6263DEVAL1Z: Evaluates the ISL6263D single-phase synchronous buck PWM controller. Incorporating Intersil's Robust Ripple Regulator (R³) technology, the evaluation board is designed for 5-25V input voltages, supports up to 12A output current, and features an on-board dynamic load generator for assessing transient response performance.
2. ISL821xMEVAL1Z Series: This evaluation board is compatible with both the ISL8210M and ISL8212M single-channel buck synchronous DC/DC power modules (not pure controllers, but integrated modules). They deliver continuous currents of up to 10A and 15A respectively, with input voltages ranging from 4.5V to 15V. Utilising Renesas' proprietary R4 technology, they exhibit exceptionally fast transient performance. The evaluation board supports flexible configuration of numerous parameters—including output voltage, switching frequency, and operating mode—via external resistors.

II. Synchronous Buck Controller Evaluation Boards
Representing Renesas' latest power architecture innovations, these boards are dedicated to achieving ultra-high efficiency in high-voltage-drop applications.
RTKA489300DE0000BU: This evaluation board assesses the RAA48930x series of single-inductor three-stage synchronous buck controllers. Its innovative three-stage buck topology significantly reduces switching losses, enhances efficiency, and minimises inductor size compared to traditional two-stage buck solutions when operating across wide input-output voltage differentials.
Key Features: Input voltage range 4.5V to 57.6V, programmable output voltage range 3V to 48V, supporting switching frequencies up to 400kHz.
Intelligent Control: On-board I²C interface enables programming, monitoring, and evaluation of key parameters via GUI tools for digital power management.

III. Wide Input Voltage, High Power Density Evaluation Boards
For industrial, telecommunications, and automotive applications, Renesas offers multiple evaluation boards supporting wide input voltage ranges and high output currents.
RAA211 Series Evaluation Boards: This is Renesas's currently most active series of wide-input synchronous buck controller evaluation boards, featuring numerous models for flexible selection.
1. High-voltage, high-current models: e.g., RTKA211650DE0000BU supports 4.5V to 60V input with 3.3V/5A output; RTKA211450DE0000BU supports 4.5V to 42V input with 3.3V/5A output. This series offers both QFN and HTSSOP package options.
2. Ultra-high input voltage models: Examples include the RTKA211820DE0000BU (QFN version) and RTKA211820DE0010BU (HTSSOP version), supporting a wide input range from 4.5V to 75V with a 3.3V/2A output. These are suitable for systems with elevated front-end bus voltages.
3. ISL8117A-related demonstration boards: The ISL8117A-LDEMO2Z demonstration board showcases the ISL8117A synchronous buck PWM controller in a buck-boost configuration. Operating within an input voltage range of 6.5V to 42V, it delivers a 12V/3A output. This provides a reference for applications requiring stable output despite potential input voltages below the output voltage.
