BD18398RUV-M
3ch Current LED Driver with SPI for Automotive
The BD18398RUV-M are 3ch synchronous buck DC-DC LED drivers with using on-time topology supporting near fixed switching frequency and fast switching duty regulation and with using average LED current feed buck topology for more accreted LED current regulation system over wide input, LED output range.
