LM536355QRNLRQ1 TI Switching Regulator | 22-VQFN-HR(5x4) | 3.5A, 36V

Product Overview

The LM536355QRNLRQ1 is a high-performance, automotive-grade synchronous buck regulator from Texas Instruments. It integrates high-side and low-side MOSFETs to deliver up to 3.5A continuous output current. With a wide input voltage range of 3.5V to 36V (42V transient), it is ideal for 12V and 24V automotive systems. The device operates at a fixed 2.1MHz switching frequency, enabling small external components and low output ripple. It features a low quiescent current of 15µA in sleep mode, making it suitable for battery-powered applications. The 22-pin VQFN-HR package (5mm x 4mm) offers excellent thermal performance.
