onsemi NCP51100A Low-Side Gate Driver


onsemi NCP51100A Low-Side Gate Driver is a 700V high side and low side driver with a 3.5A source and 3A sink current drive capability. The NCP51530 offers propagation delay, low quiescent current, and low switching current at high frequencies of operation. This device is tailored for highly efficient power supplies operating at high frequencies. The device is offered in two versions, NCP51530A or NCP51530B. NCP51530A has a typical 60ns propagation delay, while NCP51530B has a typical propagation delay of 25ns. NCP51530 comes in SOIC8 and DFN10 packages.
