RT7715 is a Digital Lite (d PWM<sup>TM</sup>) PWM controller, making a low-cost analog controller embedded with benefits of a digital controller. The controller with an innovated process technology enables system designers to select among a preprogrammed set of critical parameters, delay times, and protection features of the controller to optimize system performance, which significantly shortens project development cycle and improves component selection flexibility. In addition to the feature of programmability, the RT7715 further improves efficiency with hybrid-mode control. It can automatically switch among continuous-conduction mode (CCM), valley -switching mode (VSM), and green mode (GM) for optimal efficiency operation. The hybrid-mode control can effectively improve efficiency. The RT7715 includes comprehensive protection features, such as accurate output over-voltage (Output OVP), output under-voltage protections (Output UVP), CS pin open-circuit protection, DMAG pin open-circuit and short-circuit protections, secondary rectifier short-circuit protection (SRSP), and external over-temperature protection (External OTP).
