IC LP3783A 5V2A 10W SOP-7
LP3783A is a high performance constant voltage and constant current control chip (CV/CC) without requiring opto-coupler and the secondary control circuitry. LP3783A is the new constant voltage and constant current control chip by LP making , optimizing the driving and built-in high VCBO power triode. LP3783A/B adopting unique output line loss compensation technology, can effectively compensate the loss of output current on the output line voltage drop. It is the best choice for the high efficiency and low loss power adapter and charger.
