SDH720X is a high-precision step-down LED constant current driver circuit that supports PWM dimming function, designed for flicker-free LED smart lighting applications. SDH720X can achieve excellent dimming and output current consistency, and is suitable for use with non-isolated BUCK LED lighting systems.
SDH720X integrates HV start-up circuit and 500V power MOS, no VCC capacitors and auxiliary windings are required, and only a few peripheral components are needed to achieve excellent constant current characteristics, which greatly saves system cost and volume.
SDH720X has a high-precision current sensing circuit inside to achieve accurate LED constant current output and excellent line voltage regulation. It has complete protection functions, such as LED open circuit protection, LED short circuit protection, and over temperature regulation etc.
