LT1172CS8#TRPBF - High Efficiency Switching Regulator from Linear Technology

The LT1172CS8#TRPBF is a versatile and robust high efficiency switching regulator designed by Linear Technology, a company known for its high-performance analog integrated circuits. This component is particularly suited for applications requiring efficient voltage conversion with a minimal footprint. It is capable of delivering up to 100mA of output current with a wide input voltage range from 3V to 60V, making it an ideal choice for a variety of battery-operated and industrial power systems.

The LT1172CS8#TRPBF operates in a fixed frequency mode, using a 100kHz oscillator that keeps the switching noise out of critical frequency bands, such as AM radio, making it suitable for noise-sensitive applications. Its high switching frequency also allows the use of smaller external components, such as inductors and capacitors, thus saving space and cost on the PCB.

This regulator features a high current switch with the ability to handle 1.25A, which is internally compensated to minimize the number of external parts and simplify the design process. Additionally, the LT1172CS8#TRPBF offers various modes of operation, including Burst Mode® operation, which enhances efficiency at low output currents, and a shutdown mode that reduces the supply current to just 16µA, providing an excellent solution for power conservation in battery-powered systems.

The device is packaged in an 8-lead SOIC, which provides a compact solution for space-constrained applications. It is also available in tape and reel packaging, designated by the #TRPBF suffix, for ease of use in automated manufacturing processes.

Overall, the LT1172CS8#TRPBF is a highly flexible component that delivers performance and reliability for a wide range of power conversion applications. Its combination of high efficiency, low quiescent current, and small package size makes it an excellent choice for designers looking to optimize their power management solutions.
