The CS51412GD8 is a 1.5 A buck regulator IC designed for efficient voltage regulation in various applications. It operates at a fixed frequency of 260 kHz and accommodates input voltages ranging from 4.5 V to 40 V. This device features an external bias option, allowing it to be powered from a 3.3 V to 6.0 V supply, which enhances efficiency, particularly in high input voltage and light load scenarios. The CS51412GD8 utilizes the V2,Ñ¢ control architecture, providing fast transient response and simplified loop compensation. Key protection features include thermal shutdown, cycle-by-cycle current limiting, and frequency foldback to reduce power dissipation during short circuit conditions. The device is available in a Pb-free and RoHS compliant package, making it suitable for environmentally conscious designs. Its pin compatibility with the LT1376 allows for easy integration into existing designs.
