Description The BD9850FVM is a 1-channel DC/DC step-down switching
regulator controller, while the BD9851EFV is a 2-channel DC/DC step-down switching
regulator controller.
The BD9850FVM is adaptable for a maximum switching frequency of 2 MHz and the BD9851EFV for that of 3 MHz.
Both provide space saving in all applications.
Features 1) Adaptable for 2-MHz switching freq...
