TPSM828214SILR – TEXAS INSTRUMENTS

The TPSM828214SILR is a Texas Instruments synchronous step-down converter integrated circuit housed in a thermally enhanced 16-pin, 4×4 mm QFN package (RHL). It’s designed for high-efficiency power conversion in applications requiring a precise, low-noise 1.8V output. Operating from a 2.7V to 5.5V input voltage range, it features a 150mA continuous output current capability and employs a switching frequency of 1.2MHz, minimizing external component size. The device incorporates internal compensation, simplifying design and reducing external component count. Its architecture includes a low-dropout (LDO) regulator for improved transient response and output voltage accuracy, achieving a typical line regulation of ±0.5% and load regulation of ±1%. The TPSM828214SILR integrates features like overcurrent protection, thermal shutdown, and short-circuit protection, enhancing system reliability. Ideal for powering sensitive analog circuitry, microcontrollers, and other low-power applications in portable devices or space-constrained designs where high efficiency and low noise are paramount, it offers a significant advantage over simpler linear regulators by minimizing power loss and heat generation. The device’s small footprint and integrated protection mechanisms contribute to a robust and compact power solution.
