TPS2052BDRBR – TEXAS INSTRUMENTS

The TPS2052BDRBR is a Texas Instruments single-channel, 4A synchronous buck converter in a tiny 6-pin SOT-23 package. It operates from a wide input voltage range of 2.7V to 5.5V, efficiently regulating output voltage down to 0.8V with a maximum output current of 4A. This device features internal compensation, simplifying design and reducing external component count. Its switching frequency is internally fixed at 1.2MHz, minimizing external filter size._x000D_

The TPS2052BDRBR incorporates various protection mechanisms including overcurrent, overtemperature, and undervoltage lockout, enhancing system robustness. Its high efficiency, typically exceeding 90% at moderate load currents, minimizes power dissipation, making it suitable for space-constrained and power-sensitive applications. Common use cases include powering mobile devices, powering sensors and low-power microcontrollers from a higher voltage source, and providing regulated power in portable electronic equipment. Its small size and integrated protection features make it an advantageous choice where board space is limited and reliability is paramount. The device’s soft-start function minimizes inrush current, further contributing to improved system stability.
