ELM652DA Dual-channeling CV/CC mode 36V switching controller
■General description
ELM652DA is a dual-channeling CV/CC mode switching regulator. ELM652DA is designed to allow for
operating a wide supply voltage range from 8V to 36V.
ELM652DA features a dual-channeling CV/CC mode control functions, the CV mode (Constant voltage)
function to provide a regulated voltage output and the dual-channeling CC mode (Constant current) function
provides dual-channeling current limitation function, it is suitable for the DC / DC switching power applications
when requested the dual-channeling current limitation function.
