LMR14010ADDCR 1A, 40V SIMPLE SWITCHER Step-Down Buck Regulator IC
The LMR14010ADDCR is a compact, high-performance PWM DC-DC buck (step-down) regulator designed to deliver up to 1A continuous output current efficiently across a wide input voltage range from 4V to 40V. This device is part of Texas Instruments SIMPLE SWITCHERfamily, engineered for ease of use, high efficiency, and robust operation in automotive, industrial, and battery-powered systems.
Operating at a fixed 0.7MHz switching frequency, the LMR14010A enables the use of small inductors and capacitors, reducing overall solution size while maintaining low output ripple. The built-in Eco-mode ensures ultra-high efficiency during light-load conditions, while the shutdown current of just 1uA helps extend battery life in portable and standby systems. Internal soft-start and compensation circuits simplify design by minimizing the need for external components. The LMR14010A integrates comprehensive protection features, including pulse-by-pulse current limiting, thermal shutdown, and short-circuit protection. With a precision enable input, designers can easily implement power sequencing and controlled startup. Packaged in a low-profile SOT-23-6 (TSOT-6L) form factor, this regulator offers superior thermal performance and a compact footprint for space-constrained designs.
