The internal switch is integrated, reducing external component count for compact layouts.
The 800 mA per-channel rating sets the ceiling for LED flash current or backlight string brightness.
For existing BOM lines, procurement should plan for last-time-buy or surplus-channel sourcing.
The TPS61059DRCRG4 is obsolete and sourced through independent distribution.
