摘要： The present invention provides a light emitting device power supply circuit with dimming function and a control circuit thereof. The light emitting device power supply circuit includes: a phase-cut dimming circuit, a rectifier circuit, a transformer circuit, and a control circuit. The transformer circuit includes an auxiliary winding, which is coupled to a primary winding, for generating a bleeder current to keep a conduction current higher than a holding current and prevent the phase-cut dimming circuit from turning OFF when the phase-cut dimming circuit operates in conductive phase. The control circuit includes a waveform analysis circuit, a bleeder current control circuit, and a bleeder current source. The bleeder current source includes a linear regulator or a variable current source. The bleeder current source controls the bleeder current so that the bleeder current is generated in a continuous and non-switching manner within the conductive phase.
