Overview
The NCP1615C5DR2G is a high voltage, high efficiency Power Factor Correction (PFC) controller designed by onsemi. This component is tailored to drive PFC boost stages using the innovative Current Controlled Frequency Foldback (CCFF) method. This method ensures maximum efficiency at both nominal and light load conditions, significantly reducing standby losses. The NCP1615C5DR2G features an integrated high voltage start-up circuit, eliminating the need for external start-up components and minimizing power consumption during normal operation. It is housed in a SOIC-16 package, making it suitable for robust and compact PFC stages with minimal external components.
