Overview
Maximizing IC Performance
MT7990
APFC Primary-Side-CV Switch Power Controller
DESCRIPTION
MT7990 is a high precision primary-side constant voltage controller while achieving power factor correction.
Both of regulations of constant voltage (CV) and current - limiting (CL) are integrated into the MT7990.
MT7990 outputs constant voltage while the LED current is within the range of current limiting, it will limit the output current while the output voltage decreases as the load increases.
MT7990 can adjust the working mode automatically to save efficiency and enlarge output loading range.
It works under Quasi-Resonant Mode (QRM) at heavy loading, under Discontinuous Conduction Mode (DCM) at me...
