BM0853

BM SEMI BM0853 Green-Mode PWM Controller DESCRIPTION The BM0853 is a low cost , low startup current , current mode PWM controller with green-mode power-saving operation. The integrated functions include the leading-edge blanking of the current sensing, internal slope compensation. It would provide the users a superior DC/DC power application of higher efficiency, low external component counts, and lower cost solution for applications. The BM0853 features more protections or functions for the following characteristics : ※Add OLP (Over Load Protection) function to provide better protection performance for fault conditions like short circuit or over load. ※Modify the OVP (Over Voltage Protection) mechanism from the cycle-by-cycle mode to the hiccup mode. BM0853 is available by SOT-23-6L and DFN8L packages.
