FEATURES  
DESCRIPTION  
2
•
96% Efficient Synchronous Boost Converter  
With 1000-mA Output Current From 1.8-V  
Input  
The TPS6103x devices provide a power supply  
solution for products powered by either a one-cell  
Li-Ion or Li-polymer, or a two to three-cell alkaline,  
NiCd or NiMH battery. The converter generates a  
stable output voltage that is either adjusted by an  
external resistor divider or fixed internally on the chip.  
It provides high efficient power conversion and is  
capable of delivering output currents up to 1 A at 5 V  
at a supply voltage down to 1.8 V. The implemented  
boost converter is based on a fixed frequency,  
pulse-width- modulation (PWM) controller using a  
synchronous rectifier to obtain maximum efficiency.  
At low load currents the converter enters Power Save  
mode to maintain a high efficiency over a wide load  
current range. The Power Save mode can be  
disabled, forcing the converter to operate at a fixed  
switching frequency. It can also operate synchronized  
to an external clock signal that is applied to the  
SYNC pin. The maximum peak current in the boost  
switch is limited to a value of 4500 mA.

Fixed and Adjustable Output Voltage Options

Switch)  
•
•
•
Load Disconnect During Shutdown  
Over-Temperature Protection  
Available in a Small 4 mm x 4 mm QFN-16 or in  
a TSSOP-16 Package  
APPLICATIONS  
The converter can be disabled to minimize battery  
drain. During shutdown, the load is completely  
disconnected from the battery. A low-EMI mode is  
implemented to reduce ringing and, in effect, lower  
radiated electromagnetic energy when the converter  
enters the discontinuous conduction mode.  
•
All Single Cell Li or Dual Cell Battery Operated  
Products as MP-3 Player, PDAs, and Other  
Portable Equipment  
The device is packaged in a 16-pin QFN package  
measuring 4 mm x 4 mm (RSA) or in a 16-pin  
TSSOP PowerPAD® package (PWP).
