Since then, SparkFun has been committed to sustainably helping our world achieve electronics literacy from our headquarters in Boulder, Colorado. The chip can work directly with common triac dimmers as well as digital controls. (Courtesy of Cirrus Logic.) The rectified input voltage is sensed as a current into pin IAC. It is fixed to drive 350 mA through whatever is attached to it.
Like the BP5843A, it has a wide input voltage range of 113 to 170 VDC and can be driven from typical household power (80 to 120 VAC) and lets designers set Voltage across an eternal user-selected resistor (R11) is sensed through pin FBSENSE to control peak current through the second-stage inductor.
