Product Overview: TPS61041DBVRG4 by Texas Instruments

The TPS61041DBVRG4 is a high-frequency, boost-converter integrated circuit (IC) designed and manufactured by Texas Instruments (TI), a global leader in semiconductor solutions. This IC is specifically engineered to cater to low-power applications requiring higher output voltages from a lower voltage supply. It is widely used in battery-powered devices, handheld equipment, and other portable applications where space and power efficiency are critical.

The TPS61041DBVRG4 operates with a supply voltage ranging from 1.8V to 6V, making it versatile for use with various power sources, including single-cell lithium-ion batteries, multi-cell alkaline batteries, or regulated 3.3V and 5V power supplies. The device is capable of providing a boosted output voltage up to 28V, which is adjustable by means of external resistors.

This boost converter features a fixed switching frequency of 1MHz, allowing the use of small, low-profile inductors and ceramic capacitors to minimize the overall solution size. The high switching frequency also enables fast transient response, which is essential for applications requiring quick adjustments to changes in load conditions.

The TPS61041DBVRG4 incorporates a range of protective features ensuring the reliability and longevity of the device. These include under-voltage lockout (UVLO), over-temperature protection, and a current limit function to prevent damage from excessive current draw. Additionally, the device features a logic-level shutdown input that allows the converter to be turned off, reducing the quiescent current to less than 1µA, which is beneficial for power conservation in battery-operated devices.

Supplied in a compact 5-pin SOT-23 package, the TPS61041DBVRG4 is designed for space-constrained applications. Its small footprint and minimal external component requirements make it an ideal choice for portable electronics where efficiency and size are paramount.

Overall, the TPS61041DBVRG4 from Texas Instruments stands out as a high-performance, feature-rich boost converter that meets the needs of modern, portable electronics requiring efficient voltage step-up solutions.
