TPS62110-Q1

The TPS62110-Q1 is a highly efficient, low-quiescent current buck converter designed for automotive and industrial applications requiring reliable power management. It operates with an input voltage range of 2.5 V to 5.5 V, making it suitable for systems powered by single-cell lithium-ion batteries or 3.3 V/5 V logic supplies. The device delivers up to 1.5 A of output current while maintaining high efficiency across a wide load range, thanks to its synchronous rectification architecture that minimizes power loss. This converter features an ultra-low quiescent current of just 40 µA in light-load conditions, which is critical for extending battery life in always-on systems such as sensor nodes or remote monitoring devices. Its fixed switching frequency of 2 MHz allows the use of small external components—such as a 2.2 µH inductor and ceramic capacitors—resulting in a compact, high-density design ideal for space-constrained applications. The TPS62110-Q1 also supports pulse-frequency modulation (PFM) mode at light loads to further improve efficiency without compromising stability. Designed for robust performance in harsh environments, the TPS62110-Q1 is qualified to AEC-Q100 Grade 1 standards, ensuring reliability under automotive operating conditions including wide temperature ranges (-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 durability. The device also offers adjustable output voltage via an external resistor divider, enabling flexible integration into various voltage rails. Applications include automotive infotainment systems, telematics units, ADAS sensors, and industrial control modules where stable, efficient power conversion is essential. It supports seamless operation during cold crank events due to its ability to start up reliably even at low input voltages. With a small 3 mm × 3 mm SON package, the TPS62110-Q1 provides a space-efficient solution for portable and embedded systems demanding high performance and minimal power consumption.
