SYNCHRONOUS BOOST CONVERTER  
WITH 2A SWITCH  
FEATURES  
DESCRIPTION  
•
Synchronous (96% Efficient) Boost Converter  
The TPS6109x devices provide a power supply  
solution for products powered by either a one-cell  
Li-Ion or Li-polymer, or a two-cell alkaline, NiCd or  
NiMH battery and required supply currents up to or  
higher than 1 A. 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 0.5 A at 5  
V at a supply voltage down to 1.8 V. The im-  
plemented boost converter is based on a fixed  
frequency, pulse-width- modulation (PWM) controller  
using a synchronous rectifier to obtain maximum  
efficiency. Boost switch and rectifier switch are con-  
nected internally to provide the lowest leakage induct-  
ance and best EMI behavior possible. The maximum  
peak current in the boost switch is limited to a value  
of 2500 mA.  
With 500-mA Output Current From 1.8-V Input  
Available in a 16-Pin QFN 4 x 4 Package  
Device Quiescent Current: 20-µA (Typ)  
Input Voltage Range: 1.8-V to 5.5-V

Load Disconnect During Shutdown  
Over-Temperature Protection  
APPLICATIONS  
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.  
•
All Single Cell Li or Dual Cell Battery, or USB  
Powered Operated Products as MP-3 Player,  
PDAs, and Other Portable Equipment  
The output voltage can be programmed by an exter-  
nal resistor divider or is fixed internally on the chip.  
The device is packaged in a 16-pin QFN 4 x 4 mm  
(16 RSA) package.
