LMR23630AFDDAR | TI 3A Synchronous Buck Converter | 36V Input High-Efficiency Power Chip

Product Overview

     The LMR23630AFDDAR from Texas Instruments (TI) is a high-performance synchronous buck DC-DC converter designed for efficient step-down conversion in industrial and communication power systems. Operating from a 3.5V to 36V input range and delivering up to 3A output current, it integrates both high-side and low-side MOSFETs to achieve over 90% efficiency without external sync components.

     With a fixed 2.1MHz switching frequency, the converter offers fast transient response, low output ripple, and simplified filter design. The device includes comprehensive protection features such as UVLO, cycle-by-cycle current limit, thermal shutdown, and soft-start, ensuring robust performance. Packaged in a compact SO PowerPAD-8 (DD) form factor, the LMR23630A is ideal for space-constrained high-density designs.
