STMicroelectronics EVL101G50FLT HPF Flyback Controller
STMicroelectronics EVL101G50FLT HPF Flyback Controller is a 50W High-Power-Factor (HPF) quasi-resonant flyback converter with isolated secondary-side regulation in both constant voltage and constant current modes. This controller features a 90VRMS to 265VRMS input voltage range, a 45Hz to 66Hz frequency range, and a 50V output voltage (Iout< 1A). The controller board is based on HVLED101 and SEA05LTR current-mode controllers. This controller ensures high efficiency and compactness through a sensor-less GaN transistor and a planar transformer. The EVL101G50FLT controller board is used as a 50W single-stage LED driver or PSU. Typical applications include LED control gears, AC-to-DC adapters, and motor control pre-regulators.
