EV1600_S1_R1 is a 40V/460mA LED driver EVB based on JW1600.

The JW1600 is a primary-side control offline flyback controller with active power factor correction. It is especially designed for LED lighting system. The JW1600 controls the LED current accurately without using an opto-coupler, which can significantly simplify the design of LED lighting system. Utilizing an on-chip multiplier, the JW1600 achieves high power factor over
wide line and load ranges.

The multi-protection function largely enhances the safety and reliability of the system, including over voltage protection; short circuit protection, LED open protection, cycle-by-cycle current limit, VCC UVLO and over-temperature protection.
