91% Efficiency at 4MHz Operation  
Wide VIN Range From 2.5V to 5.5V  
The TPS8125x device is a complete MicroSiP™  
DC/DC step-up power solution intended for battery-  
powered portable applications. Included in the  
package are the switching regulator, inductor and  
input/output capacitors. Only a tiny additional output  
capacitor is required to finish the design.  
IOUT ≥550mA at VOUT = 5.0V, VIN ≥3.3V  
±2% Total DC Voltage Accuracy  
43µA Supply Current  
Best-in-Class Line and Load Transient  
The TPS8125x is based on  
synchronous step-up DC/DC converter optimized for  
battery-powered portable applications.  
a high-frequency  
VIN ≥ VOUT Operation  
Low-Ripple Light-Load PFM Mode  
True Load Disconnect During Shutdown  
Thermal Shutdown and Overload Protection  
Sub 1-mm Profile Solution  
Total Solution Size <9mm2  
9-Pin MicroSiPTM Packaging  
The DC/DC converter operates at a regulated 4-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 supply current to 43μA (typ) during light load  
operation. Intended for low-power applications, the  
TPS8125x supports more than 3W output power over  
a full Li-Ion battery voltage range. Input current in  
shutdown mode is less than 1µA (typ), which  
maximizes battery life.

Cell Phones, Smart-Phones, Tablet PCs  
Mono and Stereo APA Applications  
USB-OTG, HDMI Applications  
USB Charging Port (5V)  
The TPS8125x offers a very small solution size of  
less than 9mm2 due to minimum amount of external  
components. The solution is packaged in a compact  
(2.6mm x 2.9mm) and low profile (1.0mm) BGA  
package suitable for automated assembly by  
standard surface mount equipment.
