The ER2120QI is a high-efficiency, 2A synchronous buck regulator from Intel’s Enpirion® series, designed to provide precise voltage regulation for low-power systems. This non-isolated Point-of-Load (PoL) DC-DC converter integrates power MOSFETs within a compact 24-VFQFN package measuring 4mm x 4mm, facilitating efficient power conversion while minimizing board space. With an input voltage range of 5.5V to 14V, it delivers an adjustable output voltage between 0.6V and 12.32V, supporting a maximum output current of 2A. The ER2120QI achieves up to 95% efficiency, ensuring optimal power utilization and reduced thermal dissipation. Its switching frequency is programmable from 500kHz to 1.2MHz, allowing designers to optimize performance based on specific application requirements.

Designed for reliability, the ER2120QI operates efficiently across a wide temperature range of -40°C to 85°C, making it suitable for various environmental conditions encountered in distributed power architectures. Its surface-mount design simplifies integration into existing PCB layouts, and its compact form factor conserves valuable board space. However, it’s important to note that this product is listed as obsolete, indicating that it may no longer be in production or readily available. Designers should verify availability and consider potential alternatives for new projects.
