FEATURES  
DESCRIPTION  
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 1GHz and  
2.4GHz RF transceivers and System-On-Chip-  
solutions. The TPS62730 reduces the current  
consumption drawn from the battery during TX and  
RX mode by a high efficient step down voltage  
conversion. It 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 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 30nA current consumption to  
support sleep and low power modes of TI's CC2540  
Bluetooth Low Energy and CC430 System-On-Chip  
solutions. In this bypass mode, the output capacitor  
of the DC/DC converter is connected via an  
integrated typ. 2.1Ω Bypass switch to the battery.

Optimized For Low Output Ripple Voltage  
Small 1 × 1.5 × 0.6mm3 SON Package  
12 mm2 Minimum Solution Size  
In DC/DC operation mode the device provides a fixed  
output voltage to the system. With a switch frequency  
up to 3MHz, the TPS62730 features low output ripple  
voltage and low noise even with a small 2.2uF 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  
VIT BYP . The TPS62730 is available in a 1 × 1.5mm2  
6 pin QFN package.
