Constant-current boost driver provides ripple-free output across all modes without 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.
