It integrates a high-voltage DC-DC converter that charges a photoflash capacitor from a low-voltage supply rail, then triggers the xenon tube via an external IGBT or SCR. The part targets compact camera modules, disposable cameras, and portable strobe systems where board area and battery life are constrained. Quiescent supply current is 2 mA, keeping the standby draw low enough for battery-powered operation. No successor order code is listed on the record, so a replacement path must be evaluated — either a pin-compatible alternative within the TPS65573 family or a functionally equivalent charger IC from another supplier. For a BOM line already qualified to this part, the NRND status means the window for last-time-buy or transition planning is open. Sourcing through independent distribution is the practical channel for bridging production runs while a substitute is qualified. ## Package and thermal handling — 12-WSON exposed pad Mounting is surface-mount only. The Tape & Reel (TR) packaging is standard for automated pick-and-place assembly. No through-hole variant exists. Operating temperature range is -35°C to 85°C.","metaTitle":"TPS65573DSSR Xenon Photoflash Capacitor Charger, NRND","metaDescription":"TI TPS65573DSSR photoflash capacitor charger IC for xenon flash.
