2.4MHz, 3.5A IOUT, 75µA IQ, 10mVP-P Ripple, 3mm x 3mm DFN Linear’s growing family of 36V input-capable buck converters has the performance and features demanded by automotive, industrial and medical applications. These devices have programmable and synchronizable high frequency operation to keep externals small and high efficiency conversion to minimize thermal issues. Many devices feature micropower operation, suitable for always-on applications. With very low output ripple from no-load to full load, these converters reduce |
