LM536253QRNLTQ1 TI Switching Voltage Regulator | 22-VQFN-HR (5x4) | 36V, 2.5A, 2.1MHz

Product Overview

The LM536253QRNLTQ1 is a high-performance, automotive-grade synchronous buck converter from Texas Instruments. It operates over a wide input voltage range of 3.5V to 36V, making it suitable for 12V and 24V automotive systems. The device delivers up to 2.5A of continuous output current with excellent efficiency, thanks to its integrated low RDS(on) MOSFETs. The LM536253QRNLTQ1 is available in a compact 22-pin VQFN-HR package (5mm x 4mm) with enhanced thermal performance.
