JOULWATT is redefining power design with the release of the JW15158B, an all-in-one GaN integrated circuit. By monolithically combining a high-performance flyback controller with a 650V/1200mΩ GaN FET, JOULWATT has created a powerhouse solution for PD chargers, adapters, and versatile AC/DC power supplies.
Designed for efficiency, the JW15158B leverages an intelligent mixed PWM/PFM control strategy, optimizing performance across various load conditions. With a 110kHz max frequency and a 700V high-voltage startup—eliminating the need for bulky external resistors—this chip is built for performance and low standby power. It comes fully loaded with robust protection features, including thermal shutdown, overvoltage protection, and frequency jittering for superior EMI compliance. All of this is packed into a tiny HSOP-7 footprint, making it a game-changer for PCB space-saving.
The JW15158B is already making waves in the market. It has been successfully deployed in Bull’s 20W 2A1C GaN power strip, proving that high-power, multi-port capabilities can indeed fit into ultra-compact enclosures. For manufacturers, the JW15158B is more than just a chip; it is a competitive edge. By streamlining the BOM and reducing design complexity, it helps brands cut production costs while delivering the sleek, high-efficiency products today’s consumers demand.
