Hello,
the video at the bottom of this page about UCC25710 PWM IC says that it can achieve greater than 1% efficiency in multiple strings of LEDs...even though each series string does not have individual current control.............
AC/DC and DC/DC Power Supply - PWM Controller - UCC25710 - TI.com
..Surely this must be false?
With LEDs , every single series strng of LEDs must have its own dedicated current controller.
