Abstract

Technologies are described for a light emitting diode (LED) driver configured for powering LED(s) and having a wide input voltage range between about 100V and about 528V, high power factor, low total harmonic distortion (THD), and low output current ripple load. The LED driver has a single stage buck-boost type converter with output current regulation, an output current regulation circuit, a ripple control circuit having a transient voltage suppressor (TVS) and a parallel resonant LC filter, a power factor correction (PFC) control circuit having a digital compensation block, a PFC controller, and a gate drive IC.
