The STRG02 smart driver implements a control scheme specific to secondary-side synchronous rectification in STVCOT™ based resonant converters.
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.
The high impedance mode can be configured with the two external power MOSFETs immediately kept OFF.
The STRG02 is available in a DFN12, 3 x 3 mm package with an exposed pad.
