DESCRIPTION LC2730 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 34V 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 3.5A of continuous output current and the output current accurate to within ±7%. External compensation is not needed. It consists of inside line compensation function with 150mV at VIN (12V), and the constant current value can be set by an external resistance. In conclusion, LC2730 is a full function and high performance, high reliability buck DC-DC converter. LC2730 34V, 3.
