UNISONIC TECHNOLOGIES CO., LTD USL250X HIGH PRECISION NON-ISOLATED POWER SWITCH CMOS IC  DESCRIPTION USL250X offers comprehensive protection coverage with auto-recovery features including LED string short circuit protection, cycle-by-cycle current limiting, built-in leading edge blanking, VDD under voltage lockout (UVLO), over temperature protection(OTP), etc. Cycle-by-Cycle current limiting is offered in USL250X. The switch current is detected by a sense resistor into the CS pin. An internal leading edge blanking circuit chops off the sensed voltage spike at initial power MOSFET on state so that the external RC filtering on sense input is no longer needed. It is a high current precision, non-isolated power switch for LED lighting. It works under transition mode.
