LMR62014XMFX/NOPB Boost Switching Regulator IC 2A SOT-23-5
The LMR62014XMFX/NOPB from Texas Instruments is a compact, high-efficiency boost (step-up) switching regulator designed for space-constrained power applications requiring stable voltage conversion. Operating over an input voltage range of 2.7V to 14V, this current-mode DC-DC converter can generate output voltages up to 20V, making it ideal for portable, industrial, and communication devices. With an integrated 1.4A switch and 1.6MHz fixed switching frequency, the LMR62014 enables the use of small inductors and capacitors, achieving one of the highest power densities in its class. Its SOT-23-5 package (2.92×2.84×1.08mm) ensures minimal board space usage while maintaining excellent thermal efficiency.
Designed for efficiency and simplicity, the LMR62014 achieves greater than 90% duty cycle, allowing it to maintain regulation under low-input and high-output voltage conditions. The device includes internal frequency compensation, eliminating the need for external components and simplifying design. Protection features such as cycle-by-cycle current limiting and thermal shutdown ensure reliable operation, while a logic-level shutdown pin reduces quiescent current to less than 1uA, significantly extending battery life.
