TPS62730EVM-726 Datasheet PDF - TI

●The TPS62730EVM-726 is an evaluation module helps designers to evaluate the operation and performance of the TPS62730 step down converter. The converter is designed to deliver up to 100mA of continuous current to the output. The converter can be switched into bypass mode by grounding the ON/BYP pin or automatically with the input voltage falling to the output regulation voltage. The TPS62730 device is a high frequency synchronous stepdown dc to dc converter optimized for ultralow power wireless applications. The device is optimized to supply low power wireless sub-1GHz and 2.4GHz RF transceivers. The TPS62730 reduces the current consumption drawn from the battery during TX and RX modes by a highly efficient stepdown voltage conversion. It provides up to 100mA output current and allows the use of tiny and low cost chip inductors and capacitors. This device supports most Li ion primary battery chemistries, with an input range of 1.9 V to 3.9 V dc.
