Texas Instruments TPS62730 Step Down Converter

Texas Instruments TPS62730 is a high-frequency synchronous step down DC-DC converter optimized for ultra low-power wireless applications. TI TPS62730 DC-DC converter is optimized to supply TI low power wireless sub 1GHz and 2.4GHz RF transceivers and System-On-Chip solutions. Texas Instruments TPS62730 step down converter reduces the current consumption drawn from the battery during TX and RX mode by a highly efficient step-down voltage conversion. This device provides up to 100mA output current and allows the use of tiny and low-cost chip inductors and capacitors. With an input voltage range of 1.9V to 3.9V, the TPS62730 supports Li-primary battery chemistries such as Li-SOCI2, Li-SO2, Li-MnO2, and two-cell alkaline batteries.
