NCP3284中文资料4.5V至18V，30A（NCP3284）/35A（NC3284A）高能效DC-DC转换器，采用热增强型5mm x 6mm封装数据手册ONSEMI规格书

描述 Description

The NCP3284 is a 30A POL targeted for applications requiring high efficiency in a small board footprint. This device integrates a dc/dc controller with two highly efficient mosfets into a signal thermally enhanced 5mm by 6mm QFN package. It utilizes a patented enhanced ramp pulse modulation control architecture that delivers ultra-fast load transients that enable the reduction of external capacitors and/or provide better transient tolerances.The new architecture also improved load regulation versus traditional constant on time controllers.
