The RS53328LR from Reed Semiconductor is a high-performance synchronous buck converter designed for demanding applications requiring up to 12A of output current. With an input voltage range of 2.85V to 16V, it efficiently steps down to outputs as low as 0.6V, ideal for powering modern digital cores. The switching frequency is selectable between 600kHz and 800kHz, or can be programmed from 1MHz to 2.2MHz, allowing designers to balance efficiency and component size. Housed in a compact 21-QFN package, this converter is a powerful solution for servers, FPGAs, and telecom equipment.
- High 12A Output Current: Meets the power demands of high-performance FPGAs, ASICs, and processors.
- Wide Input Range (2.85V-16V): Flexible for various system rails from 3.3V to 12V.
- Selectable/Programmable Frequency: Optimize for efficiency or small footprint with 600kHz, 800kHz, or up to 2.2MHz.
- Low Output Voltage (0.6V): Supports the latest low-voltage digital cores for reduced power consumption.
