QH7939
General Description
The QH7939 is a single-power stage, isolated and primary side offline LED lighting regulator which achieves high power factor.
The proprietary real-current control method can control the LED current accurately from the primary side information.
It can significantly simplify the LED lighting system design by eliminating the secondary side feedback components and the opto-coupler.
The QH7939 integrates active power factor correction and works in Quasi Resonance mode (QRM) in order to reduce the
power MOSFET switching losses.
