Achieve 20-30% power savings in low-power RF devices
with TI's TPS62730 step-down converter plus integrated bypass mode for ultra-low-power wireless applications.
The TPS62730 is a high- frequency synchronous step-down DC/DC converter optimized for ultra-low-power wireless applications such as TI's low-power wireless sub 1-GHz and 2.4-GHZ RF transceivers. The device reduces the current consumption drawn from the battery during TX and RX mode by a high-efficient step-down voltage conversion.

Key Features and Benefits
- DCS Control™, an advanced regulation topology that combines the advantages of hysteric and voltage mode control architectures, enables excellent transient and AC line and load transient regulation.
- Step down converter provides excellent low-output voltage ripples over the entire load range which makes this part ideal for RF applications.
- Fixed output voltage options feature smallest solution size by using only three external components.
- Input voltage range of 1.9 V to 3.9 V supports Li-primary battery chemistries such as Li-SOCI2, LiSO2, Li-MnO2 and also two-cell alkaline batteries.
- Ultra-low-power bypass-mode with typical 30-nA current consumption supports sleep and low-power modes of modern RF transceivers.
- DC/DC operation mode provides a regulated output voltage consuming typical 25-µA quiescent current
