SLVS427C–JUNE 2002–REVISED APRIL 2004  
SYNCHRONOUS BOOST CONVERTER WITH 1.1A SWITCH AND INTEGRATED LDO  
FEATURES  
DESCRIPTION  
•
Synchronous, 95% Efficient, Boost Converter  
With 500-mA Output Current From 1.8-V Input  
The TPS6112x 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 4 cells  
Alkaline, NiCd or NiMH batteries. The devices can  
generate two stable output voltages that are either  
adjusted by an external resistor divider or fixed  
internally on the chip. It also provides a simple  
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 200 mA with supply voltages 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. The maximum peak current in the boost  
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  
•
40-µA (Typical) Total Device Quiescent Cur-  
rent  
•
•
Input Voltage Range: 1.8-V to 5.5-V  
Fixed and Adjustable Output Voltage Options  
up to 5.5-V  
•
Power Save Mode for Improved Efficiency at  
Low Output Power  
•
•
•
Low Battery Comparator  
Power Good Output  
The converter can be disabled to minimize battery  
drain. During shutdown, the load is completely dis-  
connected 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. A power  
good output at the boost stage simplifies control of  
any connected circuits like cascaded power supply  
stages or microprocessors.  
Low EMI-Converter (Integrated Antiringing  
Switch)  
•
•
•
Load Disconnect During Shutdown  
Overtemperature Protection  
Available in a Small 4mm x 4mm QFN-16 or in  
a TSSOP-16 Package  
APPLICATIONS  
The built-in LDO can be used for a second output  
voltage derived either from the boost output or  
directly from the battery. The LDO can be enabled  
separately i.e., using the power good of the boost  
stage. The device is packaged in a 16-pin QFN  
package measuring 4 mm x 4 mm (RSA) or in a  
16-pin TSSOP (PW) package.
