The XCL225/26 is a 18V synchronous buck converter with integrated coil and CoolPost structure which provides a high performance and space saving solution for demanding customer applications. Thermal performance is enhanced by the unique CoolPost structure and exposed thermal pad package. Ultra-low quiescent current ensures high efficiency also at light load conditions. Control mode can be chosen between fixed PWM or automatic PWM/PFM modes. Superior performance is further complemented by a fold-back type current limiter, adjustable soft start and power good output.
