Description
The TPS61081DRCR is a boost converter IC (integrated circuit) manufactured by Texas Instruments. It is designed to efficiently increase (boost) the voltage from a lower input level to a higher output level, which is essential in applications where the supply voltage is lower than the required operating voltage of the device. The TPS61081DRCR supports an input voltage range typically from 2.5 V to 6 V and can deliver a fixed output voltage, often adjustable up to 16 V, making it suitable for battery-powered applications.
Key features of the TPS61081DRCR include a high switching frequency, typically around 1.2 MHz, which allows for the use of smaller external components, thereby reducing the overall size of the application. It also includes features like over-current protection, thermal shutdown, and undervoltage lockout for enhanced reliability and safety. The device comes in a compact 10-pin VSON package, making it suitable for space-constrained designs. Common applications include powering RF power amplifiers, LED backlighting, and other portable electronic devices that require a boosted voltage supply.
