Cxle8311 has built-in high-precision sampling and compensation circuit, which enables the circuit to achieve constant current accuracy within ?3%, and can realize the self-adaptive of output current to inductance and output voltage, so as to achieve excellent linear adjustment rate and load adjustment rate.
The cxle8311 is internally integrated with 500V power MOSFET, which does not need secondary feedback circuit or compensation circuit. Combined with accurate and stable adaptive technology, the system's peripheral structure is very simple, and it can achieve high-precision constant current under the condition of small number of peripheral devices and loose parameter range Control, greatly saving the system cost and volume, and can ensure the consistency of LED lamp parameters in mass production. Cxle8311 has rich protection functions: output open short circuit protection, sampling resistance open short circuit protection, undervoltage protection, output over-voltage protection, over temperature adaptive regulation, etc
