Description

General part information

LT7101 Series

The LT7101 is a high efficiency, monolithic synchronous 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 1A of output current.The LT7101 features high frequency operation and a low minimum on-time that reduce inductor size and enable constant-frequency operation even at very high stepdown ratios. In addition, the LT7101 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 LT7101 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.ApplicationsBattery Chargers and CC/CV SuppliesAutomotive and Military SystemsIndustrial, Avionics and Heavy EquipmentMedical Instruments and Telecommunication Systems
