LTC1682IS8-3.3#PBF - Linear Technology

The LTC1682IS8-3.3#PBF is a high-efficiency, dual-output, charge pump DC/DC converter designed by Linear Technology, a brand known for its high-performance analog integrated circuits. This particular model is engineered to provide a fixed output voltage of 3.3V, which makes it an ideal choice for applications requiring a regulated power supply with a low dropout voltage.

Enclosed in an 8-lead SOIC package, the LTC1682IS8-3.3#PBF boasts a compact design that is suitable for space-constrained applications. It is optimized to operate from an input voltage range of 2.7V to 4.5V, making it compatible with a variety of power sources including single lithium-ion batteries, 3-cell NiCd/NiMH batteries, or regulated 3.3V and 5V power rails.

One of the key features of this product is its low quiescent current, which enhances its efficiency and makes it particularly useful in battery-powered devices where power conservation is critical. Additionally, the LTC1682IS8-3.3#PBF includes an automatic Burst Mode® operation, which further reduces power consumption during light load conditions.

The device is capable of delivering up to 100mA of output current, which is sufficient for powering small to medium-sized loads. Its high switching frequency enables the use of small external capacitors, thus reducing the overall solution footprint and saving board space.

For protection and reliability, the LTC1682IS8-3.3#PBF incorporates thermal shutdown and current limit features. These safeguards help prevent damage to the device and the powered application under abnormal conditions such as overheating or overcurrent scenarios.

In summary, the LTC1682IS8-3.3#PBF from Linear Technology is a versatile and efficient solution for generating a regulated 3.3V supply with minimal external components. Its low power consumption, small package size, and integrated protection features make it an excellent choice for portable electronics, wireless communication devices, and other applications where efficiency and space are of paramount importance.
