LMR33630CQRNXTQ1 TI Step-Down Converter | 12-VQFN-HR (3x2) | 36V, 3A, 2.2MHz

Product Overview

The LMR33630CQRNXTQ1 from Texas Instruments is a high-performance synchronous step-down (buck) DC/DC converter designed for automotive and industrial applications. It operates over a wide input voltage range of 3.8V to 36V, delivering up to 3A of continuous output current. The device is housed in a compact 12-pin VQFN-HR package (3mm x 2mm), making it ideal for space-constrained designs. With integrated high-side and low-side MOSFETs, the LMR33630CQRNXTQ1 achieves high efficiency and excellent thermal performance. Its peak current mode control architecture ensures fast transient response and stable operation with minimal external components.
