产品说明

The TPS62730 is a high frequency synchronous step-down DC-DC converter optimized for ultra low-power wireless applications. The device is optimized to supply TI's Low-Power Wireless sub 1-GHz and 2.4-GHz RF transceivers and System-On-Chip (SoC) solutions. The TPS62730 reduces the current consumption drawn from the battery during TX and RX mode by a high efficient step-down voltage conversion. The device provides an output current of up to 100 mA and allows the use of tiny and low-cost chip inductors and capacitors. With an input voltage range of 1.9 V to 3.9 V, the device supports Li-primary battery chemistries such as Li-SOCl2, Li-SO2, Li-MnO2, and also two cell alkaline batteries.

The TPS62730 features an Ultra Low-Power bypass mode with typical 30-nA current consumption to support sleep and low power modes of TI's CC2540 Bluetooth Low Energy and CC430 SoC solutions. In this bypass mode, the output capacitor of the DC-DC converter is connected through an integrated typical 2.1-Ω bypass switch to the battery.
