... IR3519SPBF * Samples only Page Synchronous MOSFET Gate Driver IC DESCRIPTION The IR3519 is extended voltage range high-speed gate driver optimized for switching power supply applications. Performance is achieved by 7V/2A gate source and 5-A sink drive capability and is capable of operating at frequencies 2MHz. The 0.4-Ω impedance of the lower gate driver holds the ...
