Description
General part information
LTC7103-1 Series
The LTC7103-1 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 4.4V to 105V and provides an adjustable regulated output voltage from 1V to VINwhile delivering up to 2.3A of output current.The LTC7103-1 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 LTC7103-1 achieves the lowest 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, pulse-skipping or forced continuous operation.The LTC7103-1 includes accurate, high speed average current programming and monitoring without the need for an external sense resistor. Additional features include a bypass LDO to maximize efficiency, fixed or adjustable output voltage and loop compensation, and a wide array of protection features to enhance reliability. Compared to the LTC7103, the LTC7103-1 is pin compatible, except that it also offers continuous inductor current mode.ApplicationsBattery Chargers and CC/CV SuppliesAutomotive and Military SystemsIndustrial, Avionics and Heavy EquipmentMedical Instruments and Telecommunication
