TPS6040SDBVR – TEXAS INSTRUMENTS

The TPS6040SDBVR is a Texas Instruments synchronous step-down converter housed in a tiny 6-pin SOT-23 package. Designed for ultra-low-power applications, it boasts a wide input voltage range of 1.8V to 5.5V, enabling operation from diverse power sources. Its output voltage is adjustable from 0.8V to V_IN – 0.3V, making it highly versatile for various load requirements. The device features a switching frequency of 1.2MHz, minimizing the size of external components. Key specifications include a quiescent current of only 25µA (typical), contributing to exceptional efficiency even at light loads. Its internal 200mA switch current facilitates powering small microcontrollers, sensors, and other low-power peripherals. The TPS6040SDBVR employs a synchronous architecture, maximizing efficiency and minimizing power loss, a crucial advantage in battery-powered devices. Soft-start functionality prevents inrush current surges, protecting sensitive components. Its small size and high efficiency make it ideal for space-constrained portable applications demanding minimal power consumption, such as wearable electronics and IoT sensors. The device’s inherent stability eliminates the need for external compensation, simplifying design and reducing board space.
