Pl LTC1265CS-5#PBF is a DC/DC switching voltage regulator typically used as a part of an integrated circuit. Specifically, it is a voltage regulator/switch with a low-dropout (LDO) regulator, a low-voltage regulator, and an inductor-less vector controller. It is typically used to regulate the output voltage of an integrated circuit, such as an audio codec, a video processor, or a power management IC. It is designed to work in extreme temperature and high-dynamic conditions and provide reliable, controlled output voltage. The LTC1265CS-5#PBF voltage regulator can be used in various applications, including: DC/DC converters, audio systems, microprocessors and memory devices, medical equipment, HVAC/R systems, automotive and industrial control systems, telecom and networking systems, as well as other embedded systems. The applications that it can serve in the industry lies from very simple, low cost designs to the most demanding topologies, with excellent performance across a wide range of frequencies.The LTC1265CS-5#PBF has a wide input voltage range, from 3V to 18V, and can output voltages of up to 50V. It has an adjustable switching frequency of up to 200 kHz, and a maximum output current of 10A. It offers excellent transient performance and a good choice of components to optimize the overall system. Additionally, it offers short-circuit protection, thermal shutdown protection, and over-voltage protection. The operating principle of the LTC1265CS-5#PBF is fairly simple. When the input voltage is lower than the output voltage, the regulator will switch off and on in order to boost the voltage up to the desired level. It utilizes a high-side P-channel MOSFET and a lowside N-channel MOSFET to perform the switching. When the input voltage is higher than the output voltage, the regulator will switch off and on in order to pull the voltage down to the desired level. In summary, the LTC1265CS-5#PBF is a versatile DC/DC switching voltage regulator that is suitable for a wide range of applications. Its wide input voltage range, adjustable switching frequencies, and maximum output current of 10A makes it very suitable for designing power management systems. Additionally, it offers excellent transient performance, short-circuit protection, thermal shutdown protection, and over-voltage protection. Last but not least, its operating principle is fairly simple, making it an excellent choice for any design.
