bw9130hv 3a led driver with dimming control ?2012 bruckewell technology corp., ltd. v - 2 www.bruckewell - semi.com/ description bw9130hv is t he monolithic ic designed for a step - down dc/dc converter capable of driving 3a load without an additional transistor. the input voltage range is up to 60v. its feedback voltage, vfb, is 200mv. the bw9130hv operates at a switching frequency of 52khz. the external shutdown function is controlled by a logic level on the on/off pin and then the circuit comes into the standby mode with istby~50 a (typ.). the on/off pin may be used for the analog dimming. as the voltage on the on/off pin is increased from 0.07v to 0.67v, the voltage on the fb pin falls from 200mv to 0. the self - protection features include a cycle - bicycles current limit and a ther mal protection. the bw9130hv is available in standard 5lto220, and 5l - to263 packages. features maximum input voltage up to 60v vfb: 200mv frequency: 52khz iled = 3.0a maximum on/off input may be used for the analog dimming thermal protection cycle by cycl e current limit typical application circuits ordering information
