LED DRVR Flyback 1-CH None 8-Pin SOIC T/R
The iW3620 is a high performance AC/DC offline LED driver which uses digital control technology to build peak current mode PWM flyback power supplies. The device operates in quasi-resonant mode at heavy load to provide high efficiency along with a number of key built-in protection features while minimizing the external component count, simplifying EMI design and lowering the total bill of material cost.
? Primary-side feedback eliminates opto-isolators and simplifies design ? Quasi-resonant operation for highest overall efficiency ? EZ-EMI ® design to easily meet global EMI standards ? Up to 130 kHz switching frequency enables small adapter size ? Very tight LED constant current regulation ? No external compensation components required ? Built-in output constant-current control with primary-side feedback for LED driver. ? Low start-up current (10 µA typical) ? Built-in soft start ? Built-in short circuit protection and output overvoltage protection ? Current sense resistor short protection ? Overtemperature Protection ? Open circuit protection ? Universal input range from 85 Vac to 264 Vac ? Single-fault protection ? Small input bulk capacitor ? Long MTBF ? High efficiency
