THE DEVICE INCLUDES TWO INTEGRATED SWITCHING FETS, INTERNAL LOOP COMPENSATION, AND 5-MS INTERNAL SOFT START TO REDUCE COMPONENT COUNT. BY INTEGRATING THE MOSFETS AND EMPLOYING THE SOT-23 PACKAGE, THE TPS54302 DEVICE ACHIEVES THE HIGH POWER DENSITY AND OFFERS A SMALL FOOTPRINT ON THE PCB. ADVANCED ECO-MODE IMPLEMENTATION MAXIMIZES THE LIGHT LOAD EFFICIENCY AND REDUCES THE POWER LOSS.   IN THE TPS54302 DEVICE, THE FREQUENCY SPREAD SPECTRUM OPERATION IS INTRODUCED FOR EMI REDUCTION. CYCLE-BY-CYCLE CURRENT LIMIT IN BOTH HIGH-SIDE MOSFET PROTECTS THE CONVERTER IN AN OVERLOAD CONDITION AND IS ENHANCED BY A LOW-SIDE MOSFET FREEWHEELING CURRENT LIMIT WHICH PREVENTS CURRENT RUNAWAY. HICCUP MODE PROTECTION IS TRIGGERED IF THE OVERCURRENT CONDITION HAS PERSISTED FOR LONGER THAN THE PRESENT TIME TPS54302DDCR SWITCHING VOLTAGE REGULATORS 4.5-V TO 28-V MAIORES DETALHES DE TPS54302DDCR NO SITE DO FABRICANTE: HTTPS://WWW.TI.COM/PRODUCT/TPS54302/PART-DETAILS/TPS54302DDCR?UTM_SOURCE=GOOGLE& TAGS DE TPS54302DDCR: TPS54302DDCR, TPS54302, TPS54302D, CI 6 TERMINAIS 4302, IC 6P 4302, CI 4302
