The LMR33630ARNXT from Texas Instruments is a high-performance synchronous buck converter belonging to the SIMPLE SWITCHER® family. It is engineered for rugged industrial applications, offering a wide input voltage range from 3.8V to 36V and capable of delivering up to 3A of output current.
This device features an adjustable output voltage ranging from 1V to 24V, making it versatile for various power supply designs. Key electrical characteristics include a peak efficiency exceeding 95%, a low operating quiescent current of 25 µA, and a maximum duty cycle of 98%. It supports multiple switching frequencies including 400 kHz, 1.4 MHz, and 2.1 MHz, and incorporates features like over-current protection and a power-good flag.
The LMR33630ARNXT utilizes a peak-current-mode control with a short minimum on-time of 68 ns. It is housed in a 12-VQFN-HR package with wettable flanks, measuring 3 mm x 2 mm, and is designed for surface mounting. The operating temperature range is -40°C to 125°C (TJ). Its design emphasizes low EMI and low switching noise, with an integrated compensation network for simplified system design.
