RT8064ZQW

Richtek Technology has introduced the RT8064ZQW, a cutting-edge synchronous step-down DC-DC converter IC designed to meet the demands of modern electronic devices. With its wide input voltage range of 2.5V to 5.5V, this IC is suitable for a variety of applications, including portable devices and consumer electronics. The integration of a high-efficiency PWM controller and two power MOSFETs minimizes external component count and simplifies the design process, reducing both cost and complexity for engineers. Operating at a fixed switching frequency of 1.2MHz, the RT8064ZQW facilitates compact circuit designs and reduces the size of external components, offering significant space and cost savings. Additionally, this IC ensures stable output voltage under varying operating conditions, thanks to its excellent load and line regulation. Moreover, built-in protection features such as over-current protection, thermal shutdown, and under-voltage lockout enhance the reliability and durability of the system, providing peace of mind for designers and end-users. Packaged in a small, thermally enhanced QFN-12 (2x2mm) package, the RT8064ZQW enables efficient PCB layouts, further contributing to space-saving and cost-effective designs
