What this part does — xenon flash charge controller
The TPS65561RGTT is a dedicated photoflash capacitor charger IC from Texas Instruments, designed to drive an IGBT and charge the main flash capacitor in xenon strobe systems. It operates from a 2.7V to 4V supply, drawing 1.3mA quiescent current — a fit for battery-powered cameras, studio strobes, and portable xenon flash modules.
Package and thermal — 16-VFQFN with exposed pad
Temperature range — commercial, not outdoor
Rated for -35°C to 70°C operating ambient. That covers indoor camera gear and studio equipment but excludes automotive cabin, outdoor flash, or cold-chain applications. No AEC-Q grade is listed; this is a commercial-grade part.
Production status — active, no obsolescence flag
ROHS3 compliant. No direct replacement or second-source is announced by TI; the base product number TPS65561 covers this variant.
