Bluetooth power rail in a 1.45x1 mm SON
The TPS62732DRYR is a fixed 1.9V output converter from Texas Instruments, designed specifically for Bluetooth (BLT) applications. Its input range of 1.9V to 3.9V covers a single Li-ion cell or a 3.3V rail, and the 1.9V output matches the core supply of many Bluetooth SoCs without an external divider or LDO.
Supply range and thermal envelope
With a single 1.9V fixed output and a 1.9V–3.9V input, this part is a drop-in for Bluetooth modules that need a regulated 1.9V rail from a Li-ion battery. Compared to the TPS53317RGBR (a DDR converter with a 1.0V input range), the TPS62732DRYR targets a different application space — Bluetooth versus DDR memory — so it is not a direct second-source. The TPS51100DGQ is also a DDR converter and does not match the 1.9V output or input range of this part.
