onsemi PMIC - PMIC - AC DC Converters, Offline Switchers - FSQ0365RN FSQ0365RN

The FSQ0365RN is a valley switching converter designed for high efficiency and low electromagnetic interference (EMI) applications. It integrates a Pulse-Width Modulation (PWM) controller and a high-voltage SENSEFET, facilitating minimal external component requirements. This device operates with a fixed frequency and includes features such as under-voltage lockout, leading-edge blanking, and built-in soft-start functionality. The FSQ0365RN supports a wide input voltage range of 85 to 265 VAC and is optimized for applications requiring low standby power consumption through advanced burst-mode operation. It provides a maximum output current limit of 1.5 A and is suitable for power supply designs in devices like DVD players, set-top boxes, and auxiliary power supplies for PCs and TVs. The product also includes multiple protection features, including overload protection, over-voltage protection, and thermal shutdown, enhancing system reliability. Engineers looking for a compact and efficient solution for offline switching applications may find the FSQ0365RN a suitable choice for their projects.
