5G169 is the four ways of lights control IC with brightness being slowing. Switch S is the lantern light string loop mode (positive / anti) selector switch, and it is in positive forward cycle when open it and reverse cycle when close it, and RP1, RP2 are used to change the external RC value of Psi ~ vs3 and SA1 ~ SA3. As 5G169 has no audio signal gN-step control, it generally applies to density decorative lights, advertising lights, disco lights, etc., and sound and light can not be synchronized. For synchronization, the audio signal is rectified, coupled and enlarged and then sent to pin 1, pin 2 or pin 4, pin 5 of 5G169. HFC55 is an 8-way lights control IC.
