LMR38010SDDAR TI Voltage Regulators - DC DC Switching Regulators
The LMR38010 is a synchronous step-down converter operating from 4.2V to 80V input and delivering up to 1A output current. It features low quiescent current of 40µA in sleep mode, making it suitable for always-on industrial and automotive systems. The device integrates high-side and low-side MOSFETs and supports switching frequencies from 200kHz to 2.2MHz. Built-in protection includes current limiting, thermal shutdown, and short-circuit protection. Selection is ideal for industrial 24V and automotive 12V/48V battery systems requiring high-voltage step-down conversion. Applications include electric vehicle power distribution, industrial sensors, battery management systems, and telecom power supplies requiring wide input voltage tolerance.
