Overview
The LMR16020PDDA is a 60 V, 2 A SIMPLE SWITCHER® step-down regulator produced by Texas Instruments. This device integrates a high-side MOSFET and is designed for a wide range of applications, including industrial, automotive, and general-purpose power conditioning from unregulated sources. It features a broad input voltage range of 4.3 V to 60 V, making it versatile for various power supply needs. The regulator is known for its ultra-low quiescent current of 40 µA in Sleep-mode and 1 µA in shutdown mode, which is particularly beneficial for battery-powered systems. The LMR16020PDDA is available in an 8-pin HSOIC package with an exposed pad for low thermal resistance.
