Mingjiada Supply Renesas Step-down (Buck) Converters, Supply Buck Controllers And Buck Regulators

Shenzhen Mingjiada Electronics Co., Ltd. — Long-term supplier of Renesas buck converters, including: buck controllers (with external FETs), buck regulators (with integrated FETs) and other products. Mingjiada Electronics stocks a wide range of mainstream models and supports both small-batch samples and large-volume orders. Backed by an efficient logistics system, we ensure rapid product delivery.

I. Renesas Buck Controllers (External FET)
Renesas Electronics’ buck controllers are designed to provide excellent step-down efficiency and flexibility for a wide range of load currents. These controllers are available in single, dual, triple and quad output configurations, offering precise voltage regulation whilst utilising external FETs to enhance scalability and thermal performance.
1. RAA489300 Series: 3-Level Buck Controller with Pass-Through Mode
The RAA489300 is a high-performance buck controller specifically designed for a 3-level buck topology. This topology delivers exceptional efficiency and significantly reduces the size of the inductor required for output voltage regulation.
Mingjiada Electronics’ recommended models:
RAA489300A3GNP
RAA489300ARGNP

2. RAA489301 Series: High-Efficiency 3-Level Synchronous Buck Controller
The RAA489301 is a 3-level buck voltage controller that provides seamless transition between VOUT < VIN/2, VOUT = VIN/2 and VOUT > VIN/2. The RAA489301 offers a wide regulated output voltage range and high efficiency. It also significantly reduces the size of the inductor.

3. ISL81100 Series 100V Synchronous Buck Controller
The ISL81100 is a 100V synchronous buck controller that provides a buck output for a wide range of applications in industrial and general-purpose sectors. The ISL81100 utilises fixed-frequency peak current-mode PWM control.
Mingjiada Electronics recommended models: ISL81100FRTZ

II. Renesas Step-Down Regulators (with Integrated FET)
Renesas Electronics offers a comprehensive portfolio of step-down regulators with integrated FETs, delivering efficient step-down conversion in a compact design. These regulators simplify power supply design by reducing the number of external components and delivering high performance for a wide range of applications.
1. RAA808015 Series 5.5V 5A Compact Single-Channel DC/DC Synchronous Buck Regulator
The RAA808015 is a compact single-channel DC/DC synchronous buck regulator. To meet the requirements of applications with input rails ranging from 2.7 V to 5.5 V and a 5 A load, the regulator requires a high switching frequency to minimise inductor size, enhance transient response and improve light-load efficiency. The regulator utilises a COT IP design to improve transient response and employs PFM technology to enhance light-load efficiency.

RAA808015AGNP
RAA808015BGNP

2. RAA211803 Series 3.3V, 300mA, Ultra-Low Quiescent Current, DC/DC Buck Regulator
The RAA211803 is a compact, easy-to-use, ultra-low quiescent current (IQ) step-down converter featuring a wide input voltage range of 7V to 80V, an output current of up to 300mA, and a fixed output voltage of 3.3V.
Mingjiada Electronics recommended model: RAA2118034GP3

3. RAA211230 Series 24V 3A Synchronous Buck Regulator with Current-Mode COT
The RAA211230 is an integrated 24V 3A synchronous buck regulator featuring current-mode constant on-time (COT) control. The RAA211230 offers comprehensive protection features, including input under-voltage lock-out (UVLO), over-current protection (OCP), output under-voltage protection (OUVP) and over-temperature protection (OTP).
Mingjiada Electronics’ recommended model: RAA2112304GP3
