LM3215TL/NOPB TI Power Management IC | 2.7V-5.5V, 1.5A Step-Down Converter

Product Overview

The LM3215TL/NOPB from Texas Instruments is a high-efficiency, 1.5A step-down (buck) DC-DC converter designed for portable and battery-powered applications. It operates over a wide input voltage range of 2.7V to 5.5V, making it ideal for single-cell Li-Ion, multi-cell alkaline, or NiMH battery-powered systems. The device integrates a low RDS(on) N-channel MOSFET switch and synchronous rectifier to achieve up to 95% efficiency. With a fixed 1.5MHz switching frequency, the LM3215TL/NOPB allows the use of small, low-cost inductors and capacitors, minimizing the overall solution footprint. The device is available in a tiny 6-pin micro SMD package, suitable for space-constrained applications.
