SPMICRO JW1796
JW1796 is supplied from the MOSFET drain directly, so the auxiliary winding is eliminated, which can light up the LED within 100mS. With unique sampling techniques, JW1796 has multi-protection functions which can largely enhance the safety and reliability of the system, including VDD UVLO, inductor short protection, LED short protection and over-temperature protection.
