The FAN6230A is a secondary-side synchronous rectifier (SR) MOSFET controller for high efficiency applications. It has internal shunt regulator with low bias current and internal charge pump circuit to reduce external part counts, total cost and overall system power consumption. With the internal charge pump circuit, the FAN6230A guarantees stable operation of SR switching even with low bias voltage in CC regulation. The FAN6230A also features internally adjustable cable compensation that helps maintain precise constant voltage regulations at the end of cable.Unlike the traditional SR current sensing methods, which measure the SR MOSFET drain voltage that is sensitive to the noise introduced by poor PCB layout. The FAN6230A utilizes a novel Linear-Prediction Timing Control (LPC) circuit to estimate the SR current zero crossing instant without additional current sensing circuitry. While running in Green Mode, the FAN6230A shuts off the SR MOSFET and lowers its bias supply current to 500 µA, so overall power consumption of the system is further reduced.
