STPRDC01

同步整流器智能驱动器; • Dual low-side driver for N-Channel MOSFETs \n• 4 A sink/source current \n• Operating frequency up to 1 MHz \n• Predictive ZCS / ZVS control \n• High-impedance control \n• START input \n• DFN12, 3x3 mm package;

The STPRDC01 smart driver implements a control scheme specific to secondary-side synchronous rectification in STVCOT™-based resonant / non-resonant converters.\n\n It provides two high current gate drive outputs, each capable of driving one or more N-channel Low-Side Power MOSFETs. Both gate driver are controlled by the combination of START input and the embedded predictive ZCD/ZVS control assuring the two external power MOSFETs to be switched in zero-voltage / zero-current conditions to achieve high efficiency power conversion.\n\n High-Impedance mode can be configured with the two external Power MOSFETs immediately kept OFF.\n\n The STPRDC01 is available in DFN12, 3x3 mm package with exposed pad.\n\n
