High-Performance Buck Converter for HDD, LPDDR, and SoC Power Supply
Richtek’s RT5744A/B is a high-performance 4A, 2.4MHz synchronous Buck converter specifically designed for powering HDDs, LPDDR3/4/5, and SoCs. Operating from the 2.5V to 5.5V input voltage range, it delivers a precisely regulated output voltage from 0.27V to 1.4V, making it ideal for advanced system power system.
RT5744A/B Product Key Features
✅ Flexible Output Configuration
VSEL pin allows system-level control of two pre-set output voltages.
Customized factory-programmable default voltage options offer design flexibility and system optimization.
✅ I²C Dynamic Voltage Scaling for Enhanced Efficiency and Stability
It supports Dynamic Voltage Scaling (DVS) via I²C for real-time voltage adjustment based on output load.
Automatically switching between PFM mode under light load and fixed-frequency PWM mode under heavy load optimizes efficiency and performance.
Integrated DVS slew rate control ensures smooth voltage transitions, minimizing output ripple.
✅ Robust System Protection
Built-in protection features including UVLO, Over-Temperature Protection, and Over-Current Protection enhance system reliability.
Compact WL-CSP package enables high power density, ideal for space-constrained applications.
A user-friendly GUI tool is also available for easy setup. For more details or customization needs, feel free to contact your local Richtek sales office.
