Product Overview: TPS61086DRCR from Texas Instruments

The TPS61086DRCR is a high-frequency, high-efficiency boost converter integrated circuit (IC) from the renowned semiconductor manufacturer Texas Instruments (TI). Designed to meet the needs of portable electronics that require high-voltage outputs from low-power sources, the TPS61086DRCR is an ideal solution for a wide range of applications including but not limited to personal digital assistants (PDAs), wireless handsets, and digital cameras.

This compact IC is housed in a small 10-pin SON package, making it suitable for space-constrained applications. The TPS61086DRCR operates with a switch frequency of up to 1.2MHz, which allows for the use of small, low-profile inductors and capacitors to minimize the size of the power supply solution. Additionally, the high-frequency operation can reduce noise and interference in sensitive RF and audio applications.

The TPS61086DRCR features a wide input voltage range from 2.3V to 6V, making it compatible with various power sources, including single-cell lithium-ion batteries. The device can provide an adjustable output voltage up to 27V, allowing designers to use it in a variety of configurations and with multiple LED strings, for instance. The boost converter also incorporates a 2A, 0.2-ohm power switch which contributes to its high output current capability.

With its high efficiency, the TPS61086DRCR can deliver a high output current, even at high output voltages, without overheating. It also includes a range of features to protect the end application, such as thermal shutdown, over-voltage protection, and under-voltage lockout. The device also supports selectable soft start and has a true load disconnect feature which isolates the load from the power source when disabled.

In summary, the TPS61086DRCR from Texas Instruments is a versatile and efficient solution for boosting low voltages to higher levels in compact electronic devices. Its combination of a high-frequency operation, adjustable output, and integrated protection features make it an excellent choice for designers looking to optimize power management in their next project.
