S4225MB

Sample application

Sketch

S4225MB is a CCT controller embedded with EEPROMmemory cells, which can storage the state afterpowering off. It sets a state-switching-window time Tsw(internal timing, Typ 6.4S).Turning on the light within ashort time after turning off it, if the OFF time is less thanTsw , the light will transfer to the next CCT state;Otherwise the light will display the CCT state beforepowering off. It is very convenient to use.

Advantage

Three states loop:L1-L2-(L1+L2)/2

Integrates EEPROM cells to storage state

State storage time over 10 years

More than 100000 switching times(memory function works)

Integrates two 400V Thyristors

Switching OFF/ON twice within 1S to reset state

State-switching-window time(internal timing)is 6.4S

Built in voltage limiting circuit for wide output power range

compatible with Flyback, Buck, Buck-Boost,linear and other LED driving applications
