LMR51420XDDCR – 4V to 36V, 2A Synchronous Step-Down Converter | Texas Instruments
The Texas Instruments LMR51420XDDCR is a 2A synchronous buck converter with an input range of 4V to 36V, designed for high-efficiency, compact DC-DC power supplies. Featuring integrated high-side and low-side MOSFETs, it provides up to 95% efficiency and requires minimal external components. Its constant on-time (COT) control ensures fast transient response and excellent load regulation across operating conditions.
Operating at a fixed 2.1MHz switching frequency, this converter supports smaller passive components for a compact PCB design. With low quiescent current, internal compensation, and protection features like cycle-by-cycle current limiting, UVLO, and thermal shutdown, it’s ideal for space-constrained and power-sensitive designs.
