LTC71031 Rev. BFor more information FeedbackTYPICAL APPLICATION FEATURESDESCRIPTION105V, Low EMI Synchronous Step-Down RegulatorThe LT C 7103 is a high efficiency, monolithic synchro-nous step-down DC/DC converter utilizing a constant frequency, average current mode control architecture. It operates from an input voltage range of to 105V and provides an adjustable regulated output voltage from 1V to VIN while delivering up to of output current. The LTC7103 features high frequency operation and a low minimum on-time that reduce inductor size and enable constant-frequency operation even at very high step-down ratios. In addition, the LTC7103 achieves the low-est possible dropout voltage with 100% maximum duty cycle operation. During light load operation, converter efficiency and output ripple can be optimized by selecting Burst Mode or pulse-skipping LTC7103 includes accurate, high speed average cur-rent programming and monitoring without the need for an external sense resistor.
