概要
The EVLHVLED007W35F supplies a stable and isolated 48 V voltage bus suitable for secondary side circuitry (e.g., LED current generators) for a total output power of 35 W when a wide range of input voltages is applied at its input. An auxiliary 12 V output is also present to supply small circuits which absorb a maximum current of 15 mA.
Thanks to an STMicroelectronics patented control embedded on HVLED007, the main feature of this design is the very low input current distortion (THD) in flyback converter operating in Transition mode (Quasi-Resonant).
Fast startup and protections with auto-restart are available for safe operation in lighting environments.
