Texas Instruments TPS62733EVM-726

Step Down Converter with Bypass Mode for Ultra Low Power Wireless Applications Evaluation Module Board

The TPS62730EVM-726 evaluation module (EVM) helps designers evaluate the operation and performance of the TPS62730 step-down converter. The user’s guide describes the TPS62730 evaluation module, how to perform a stand-alone evaluation or interface with a host or system. The converter is designed to deliver up to 100 mA 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-dc converter optimized for ultralow-power wireless applications. The device is optimized to supply TI’s low-power wireless sub-1-GHz and 2.4-GHz 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 100-mA 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. The TPS62730 features an ultralow-power bypass mode with a typical 30 nA current consumption to support low-power modes of modern RF transceivers. In this bypass mode, the input is connected the VOUT pin via an internal 2-Ω bypass FET. The device automatically enters bypass mode when the input (battery) voltage falls to the bypass transition threshold.
