The SiC641ACD-T1-GE3 Power Management Specialised - PMIC 55A DrMOS 3.3V PWM PowerPAK MLP31-55 is a 3.3V 55A synchronous rectified buck regulator designed and manufactured by Vishay. It is designed to offer a typical efficiency of 92% with a single input and output, while the dual input version boosts efficiency to 99%. The wide input voltage range supports applications requiring up to 24V and the integrated switching regulator, PWM controller and power stage components provide small size solution for power conversion. The integrated startup regulator eliminates the need for an external startup circuit, so the device is plug-and-play by adding just a few external components. The device also features built-in current limits, internal thermal protection and soft start, making it highly reliable and safe for a wide range of applications.
