- Wide Input Voltage Range: Accepts 2.85V to 16V, providing flexibility for various power sources including multi-cell batteries.
- High-Frequency Operation: Up to 2.2MHz switching reduces inductor and capacitor size, saving board space.
- Adjustable Output: Output from 0.9V to 5.5V allows use across different logic and core voltage levels.
High-Current Point-of-Load (POL) Converters
With a 12A output capability and 0.9V to 5.5V output range, the RS53328HR is ideal for powering FPGAs, ASICs, and DSPs in networking and computing equipment where high current at low voltage is required.
Battery-Powered Portable Devices
The wide 2.85V to 16V input range supports multi-cell Li-ion battery packs. High efficiency at light loads extends battery life in portable instruments and handheld scanners.
Distributed Power Systems
In telecom and server racks, this buck converter efficiently steps down 12V or 5V intermediate bus voltages to core voltages, reducing heat and improving system reliability.
Industrial Control Systems
Its wide input range accommodates unregulated 5V to 15V supply rails found in industrial sensors, PLCs, and motor control boards, providing a stable regulated output.
Automotive Infotainment
Operating from 3.3V to 16V, it can power infotainment processors and displays directly from the car battery or a pre-regulated rail, handling load transients effectively.
Storage and SSD Drives
The high 12A current and fast transient response make it suitable for powering NAND flash memory arrays and controllers in enterprise SSDs and RAID controllers.
