Datasheet - EVLHV101PSR50W

COO (Country of Origin):: IT

50 W converter using HVLED101 quasi resonant HPF flyback controller with primary side regulation

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 behaviour is implemented.

Feature

• Input voltage: Vin: 90 - 265 Vrms, f: 45-66 Hz

• Output voltage 60 V / 833 mA

• High power factor, low THD

• Efficiency > 50% in stand-by (Pout = 240 mW)

• 4 points (25%, 50%, 75%, 100% load) average efficiency > 91%

• Frequency foldback with valley locking for noise-free operation

• TAMB-MAX = 60 °C

• Open load voltage limiting (< 65V)

• Short-circuit protection with auto restart

• NTC overtemperature protection for switching MOSFET

• Safety: Acc. to EN60065

• EMI: Acc. to EN55022 – conducted emissions

• RoHS compliant
