TPS51200QDRCRQ1 – TEXAS INSTRUMENTS

The TPS51200QDRCRQ1 is a 40V, 2A synchronous step-down converter from Texas Instruments, packaged in a 16-pin QFN (4x4mm) package. It employs a hysteretic control architecture, enabling fast transient response and minimizing output voltage ripple, crucial for applications demanding tight voltage regulation. The device operates from a wide input voltage range of 4.5V to 40V, making it suitable for automotive and industrial applications with fluctuating power supplies. Its integrated 2A switch and 150mΩ internal MOSFETs contribute to high efficiency, typically exceeding 90% across its operating range. The TPS51200QDRCRQ1 features adjustable output voltage via external resistors, allowing for flexible design configurations. Moreover, its internal soft-start functionality prevents inrush current surges during power-up, protecting sensitive circuitry. Common use cases include powering microcontrollers, digital signal processors, and other low-power loads in demanding environments requiring robust voltage regulation and high efficiency, where its small form factor is also advantageous. The device’s inherent robustness and efficiency make it a superior choice compared to simpler linear regulators in applications needing high power conversion efficiency and fast transient response.
