SLVS431A–JUNE 2002–REVISED AUGUST 2003  
SYNCHRONOUS SEPIC / FLYBACK CONVERTER WITH 1.1A SWITCH  
AND INTEGRATED LDO  
FEATURES  
DESCRIPTION  
•
Synchronous, Up To 90% Efficient, SEPIC  
Converter With 300-mA Output Current From  
2.5-V Input  
The TPS6113x devices provide a complete power  
supply solution for products powered by either a  
one-cell Li-Ion or Li-Polymer or a two up to four-cell  
Alkaline, NiCd or NiMH batteries. The device can gen-  
erate two regulated output voltages that are either  
adjusted by an external resistor divider or fixed  
internally on the chip. It also provides a simple and  
efficient buck-boost solution for generating 3.3 V out of  
a one-cell Li-Ion or Li-Polymer battery at a maximum  
output current of at least 300 mA with supply voltages  
down to 1.8 V. The implemented SEPIC converter is  
based on a fixed frequency, pulse-width-modulation  
(PWM) controller using a synchronous rectifier to ob-  
tain maximum efficiency. The maximum peak current in  
the SEPIC switch is limited to a value of 1600 mA.  
•
Integrated 200-mA Reverse Voltage Protected  
LDO for DC/DC Output Voltage Post Regu-  
lation or Second Output Voltage  
•
•
Dual Input or Dual Output Mode  
Available in a 16 pin QFN 4x4 or in a  
TSSOP-16 Package  
•
40-µA (Typical) Total Device Quiescent Cur-  
rent  
•
•
Input Voltage Range: 1.8-V to 5.5-V  
Adjustable Output Voltage up to 5.5-V, Fixed  
Output Voltage Options  
The converter can be disabled to minimize battery  
drain. During shutdown, the load is completely discon-  
nected from the battery. A low-EMI mode is im-  
plemented to reduce ringing and in effect lower radi-  
ated electromagnetic energy when the converter enters  
the discontinuous conduction mode. A power good  
output at the SEPIC stage provides additional control of  
any connected circuits like cascaded power supply  
stages or microprocessors.  
•
Power Save Mode for Improved Efficiency at  
Low Output Power  
•
•
•
•
High Efficient Li-Ion to 3.3-V Conversion  
Low Battery Comparator  
Power Good Output  
Low EMI-Converter (Integrated Antiringing  
Switch)  
The built-in LDO can be used for a second output  
voltage derived either from the SEPIC output or directly  
from the battery. The output voltage of this LDO can be  
programmed by an external resistor divider or is fixed  
internally on the chip. The LDO can be enabled separ-  
ately i.e., using the power good of the SEPIC stage.  
•
•
Load Disconnect During Shutdown  
Overtemperature Protection  
APPLICATIONS  
•
All Single Cell Li, Dual or Triple Cell Battery or  
USB Powered Products as MP-3 Player, PDAs,  
and Other Portable Equipment  
The device is packaged in a 16-pin QFN 4 x 4 mm  
(16RSA) or in a 16-pin TSSOP (16 PW) package.
