The TPS65835RKPT is a dedicated power management IC from Texas Instruments, designed specifically for Active Shutter 3D Glasses. It integrates the supply sequencing and voltage regulation needed to drive LCD shutter lenses from a single battery cell. It operates from a 2.5V to 6.4V supply rail, covering one Li-ion cell or two alkaline cells in series. The quiescent current is 39µA, which keeps the drain on the battery low during idle periods—important for a wearable that may sit in standby between uses.
Package and thermal layout notes
Housed in a 40-VFQFN with exposed pad, 5x5 mm body. Operating temperature is rated 0°C to 60°C—commercial grade, so this part is intended for indoor consumer electronics, not automotive or industrial enclosures where ambient exceeds 60°C.
This is a single-source TI part—no direct pin-compatible second source is listed, so plan for sole-source risk in your supply chain.
