LTC7103HUHE#PBF

LTC7103 is a high efficiency, monolithic synchronous step-down DC/DC converter utilizing a constant frequency, average current mode control architecture. This device 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, this device 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 or pulse-skipping operation. This device includes accurate, high speed average current programming and monitoring without the need for an external sense resistor. It is used in application such as battery chargers and CC/CV supplies, automotive and military systems, industrial, avionics and heavy equipment, medical instruments and telecommunication systems etc.
