Introducing the TPS61073DDCR from Texas Instruments

The TPS61073DDCR is a high-performance, adjustable, step-up DC/DC converter designed by Texas Instruments to cater to a wide range of applications that require efficient voltage boosting capabilities. This compact device is ideal for portable electronics, where space is at a premium and power efficiency is crucial.

With its input voltage range of 0.9V to 6.5V, the TPS61073DDCR is versatile enough to be powered by single-cell batteries or other low-voltage power supplies, making it a perfect choice for devices like handheld medical equipment, wireless headsets, and battery-powered accessories. The output voltage is adjustable from 1.8V to 12V, providing the flexibility to power a variety of circuits that require different voltage levels.

The TPS61073DDCR boasts an impressive efficiency level of up to 96%, thanks to its 1.2MHz fixed-frequency pulse-width modulation (PWM) operation, which reduces the size of external components and helps minimize power losses. Additionally, the device features a typical start-up voltage of 0.9V and can operate down to 0.8V after start-up, ensuring that it can squeeze out energy from batteries that are nearly depleted.

Protection features are also built into the TPS61073DDCR to safeguard your application from potential damage. These include over-temperature protection, over-voltage protection, and under-voltage lockout, ensuring reliable operation under various conditions. The device also includes a power-save mode, which enhances efficiency at light loads, and a bypass mode, which allows the input voltage to directly pass through when appropriate.

Offered in a tiny 6-pin SOT-23 package, the TPS61073DDCR is designed for space-constrained applications. Its small footprint and low profile make it an excellent choice for portable and miniaturized electronics where efficiency and size are critical.

Whether you're developing a new portable gadget or looking to improve the power efficiency of an existing device, the TPS61073DDCR from Texas Instruments provides a robust, flexible, and efficient solution for your voltage step-up needs.
