TPS6125x 3.5-MHz High Efficiency Step-Up Converter In Chip Scale Packaging  
The TPS6125x operates at a regulated 3.5-MHz  
switching frequency and enters power-save mode  
operation at light load currents to maintain high  
efficiency over the entire load current range. The  
PFM mode extends the battery life by reducing the  
quiescent current to 37 μA (typ) during light load  
operation.

Wide VIN Range From 2.3 V to 5.5 V  
VIN ≥ VOUT Operation  
In addition, the TPS6125x device can also maintain  
its output biased at the input voltage level. In this  
mode, the synchronous rectifier is current limited  
allowing external load (e.g. audio amplifier) to be  
powered with a restricted supply. In this mode, the  
quiescent current is reduced to 21 µA. During  
shutdown, the load is completely disconnected from  
the battery. Input current in shutdown mode is less  
than 1 µA (typ), which maximizes battery life.  
IOUT ≥ 800 mA at VOUT = 4.5 V, VIN ≥ 2.65 V  
IOUT ≥ 1000 mA at VOUT = 5.0 V, VIN ≥ 3.3 V

The TPS6125x offers a very small solution size due

3 Description  
90  
The TPS6125x device provides a power supply  
solution for battery-powered portable applications.  
Intended for low-power applications, the TPS6125x  
supports up to 800-mA load current from a battery  
discharged as low as 2.65V and allows the use of low  
cost chip inductor and capacitors.

With a wide input voltage range of 2.3 V to 5.5 V, the  
device supports applications powered by Li-Ion  
batteries with extended voltage range. Different fixed  
voltage output versions are available from 3.15 V to  
5.0 V.
