17mm 5A constant-current buck driver delivers flat, ripple-free current regulation across all mode levels with no PWM flicker.

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.
