FL7733A Description
The FL7733A is a highly−integrated PWM controller with advanced Primary−Side Regulation (PSR) technique to minimize ponents in low−to−mid−power LED lighting converters. Using an innovative TRUECURRENT® technology to provide tight tolerance constant−current output, this LED driver enables designs with constant current (CC) tolerance of less than ±1% over the universal line voltage range to meet stringent LED...
