TI TPS62730DRYT

Преобразователь, Bluetooth (BLT)1,9 В ~ 3,9 В2.1V

Overview

The TPS62730DRYT 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 TPS62730DRYT 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.

In DC-DC operation mode the device provides a fixed output voltage to the system. With a switch frequency up to 3 MHz, the TPS62730 features low output ripple voltage and low noise even with a small 2.2-μF output capacitor. The automatic transition into bypass mode during DC-DC operation prevents an increase of output ripple voltage and noise once the DC-DC converter operates close to 100% duty cycle. The device automatically enters bypass mode once the battery voltage falls below the transition threshold VITBYP . The TPS62730 is available in a 1 × 1.5-mm2 6-pin USON package.
