DOB explosion model S5542S single-chip non-isolated switch color matching constant current chip
S5542S single chip non-isolated switch color matching constant current chip
Product introduction:
S5542S is an integrated high-precision non-isolated LED constant current and switching color temperature control chip developed for DOB overclocking applications. The chip works in the current and inductance critical mode, suitable for non- The isolated step-down LED constant current color-tuning power supply can realize color-tuning temperature through the wall switch.
