LT7101EUHE#PBF

LT®7101 is a high efficiency, monolithic synchronous step-down DC/DC converter utilizing a constant frequency, average current mode control architecture. It 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. During light load operation, converter efficiency and output ripple can be optimized by selecting Burst Mode, pulse-skipping or forced continuous operation. It 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. Typical applications are battery chargers and CC/CV supplies, automotive and military systems, industrial, avionics and heavy equipment, medical instruments and telecommunication systems.
