FAN6961DZ

Overview

The FAN6961DZ is a Green mode Power Factor Correction (PFC) Forward PWM Controller manufactured by onsemi. It utilizes Boundary Conduction Mode (BCM) to enhance efficiency across varying load conditions. The component is housed in an 8-pin DIP package designed for through-hole mounting. It operates within a temperature range of -40°C to +125°C and features low standby power consumption with a typical operating supply current of 10 µA. The device supports high-power density designs suitable for AC/DC adapters.
