Not detected / listed

Constant current buck circuit without low-frequency flicker or PWM.

Why this matters: Buck and boost drivers step down or step up voltage efficiently using switching inductors, maintaining flat regulated output as cell voltage drains rather than dimming progressively like FET/linear direct drives.
