产品概述
描述
The EVLHV101PSR50W is intended to provide a stable and insulated 60 V voltage for a maximum power of 50 W.
It can be used as a standalone power supply or as a front end stage in a dimmable (or non-dimmable) off line LED driver.
A very high power factor, low THD and low BOM cost are obtained from this demonstration board thanks to the features of the HVLED101, which adopts frequency foldback with valley locking operation to reduce the switching losses and minimize acoustic noise.
Extremely low input power is obtained at no-load.
Input voltage variations, excessive input voltage (overvoltage like surges or bursts) and insufficient input voltage are managed by the HVLED101 protections, which improve the reliability of the application.
Output short-circuit and overload protection with auto restart behavior is implemented.
