STRG02

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, 3 x 3 mm package;

The STRG02 smart driver implements a control scheme specific to secondary-side synchronous rectification in STVCOT™ based 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 drivers are controlled by the combination of the START input and 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 The high impedance mode can be configured with the two external power MOSFETs immediately kept OFF.\n\n The STRG02 is available in a DFN12, 3 x 3 mm package with an exposed pad.\n\n
