LC2740 42V, 100% Duty Cycle CC&CV Buck Converter DESCRIPTION LC2740 has an optimum input voltage, step-down converter that operates in either CV (Constant Output Voltage) mode or CC (Constant Output Current) mode. The maximum input voltage is up to 42V and the operation input voltage from 8.5V to 32V. MOSFET, what build in 35mΩ High-Side and 25mΩ Low-Side, could deliver up to 3A of continuous output current and the output current accurate to within ±7%. No external compensation component requirement. The line compensation and the constant current can be set by an external resistance. Independent output voltage protection suits for BC1.2 and QC2.0/3.0 dual channel output voltage. In conclusion, LC2740 is a full function and high performance, high reliability buck DC-DC converter.
