Vishay Precision Group Dc/dc Conv, Sync Buck, Powerpak Mlp55-27; Topology Vishay SIC473ED-T1-GE3

The SiC47x series, specifically the SiC473 model, is a synchronous buck DC/DC converter designed for a wide input voltage range of 4.5 V to 55 V and capable of delivering up to 5 A of output current. It features integrated high side and low side power MOSFETs, allowing for high efficiency with peak efficiencies reaching 98%. The output voltage is adjustable down to 0.8 V, making it suitable for various applications including computing, consumer electronics, and industrial systems. This converter operates at a switching frequency of up to 2 MHz and offers ultrafast transient response with minimal output capacitance. It supports multiple operation modes, including forced continuous conduction and power save modes, enhancing its versatility. The device includes comprehensive protection features such as overcurrent protection, output overvoltage protection, and thermal shutdown, ensuring reliable operation. The SiC473 is housed in a compact PowerPAK MLP55-27L package, which is lead-free and RoHS compliant. It is also supported by design tools from Vishay, including online simulation and component calculators, facilitating easier integration into designs.
