TPS54116-Q1

The TPS54116-Q1 is a high-efficiency, synchronous buck converter designed for automotive and industrial applications, featuring an input voltage range of 4.5 V to 28 V, making it suitable for a wide variety of power supply scenarios. It delivers up to 1.5 A of continuous output current, ensuring reliable performance under demanding load conditions. The device integrates both high-side and low-side MOSFETs, reducing external component count and simplifying design while improving efficiency across the operating range. This converter operates with a fixed frequency of 500 kHz, enabling optimal performance with minimal output ripple and efficient use of external components such as inductors and capacitors. Its advanced control architecture supports pulse-width modulation (PWM) mode for high efficiency at full load and automatic transition to pulse-skipping mode at light loads, minimizing quiescent current and maintaining efficiency even under low-power conditions. This feature is particularly beneficial in battery-powered or energy-sensitive systems. Designed to meet AEC-Q100 Grade 1 qualification standards, the TPS54116-Q1 ensures robust reliability in harsh automotive environments, including wide temperature ranges from –40°C to +125°C. It includes comprehensive protection features such as over-current protection (OCP), thermal shutdown, and undervoltage lockout (UVLO), enhancing system safety and longevity. The device also supports soft-start functionality to reduce inrush current during startup, preventing stress on the power supply and connected components. The TPS54116-Q1 is ideal for powering microcontrollers, sensors, and communication modules in automotive electronics, including infotainment systems, ADAS (Advanced Driver Assistance Systems), telematics, and body control modules. Its compact 8-pin SOIC package allows for space-efficient board layouts, while its low EMI characteristics simplify compliance with electromagnetic compatibility regulations. Additionally, the device offers flexibility in compensation and feedback network design, enabling engineers to tailor performance to specific application needs without compromising stability or response time. With integrated diagnostics and status monitoring via the enable pin and fault flag outputs, the TPS54116-Q1 provides designers with enhanced visibility into system health, supporting predictive maintenance and fault logging in mission-critical applications. Overall, this device combines high efficiency, robust protection, and automotive-grade reliability in a single, easy-to-use solution.
