BLL2740
BLL2740 is 100% Duty Cycle CC&CV Buck Converter manufactured by BELLING.
DESCRIPTION
42V, 100% Duty Cycle CC&CV Buck Converter
FEATURES
BLL2740 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 55mΩ high-side and 30mΩ low-side, could deliver up to 3.5A of continuous output current and the output current accurate to within ±7%.
No external pensation ponent requirement. The line pensation 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, BLL2740 is a full function and high performance, high reliability buck DC-DC converter.
