17-V, 1.5-A, SYNCHRONOUS STEP-DOWN CONVERTER  
FEATURES  
DESCRIPTION  
High-Efficiency Synchronous Step-Down  
Converter With up to 95% Efficiency  
The TPS6211x devices are a family of low-noise  
synchronous step-down dc-dc converters that are  
ideally suited for systems powered from a 2-cell Li-ion  
battery or from a 12-V or 15-V rail.  
3.1-V to 17-V Operating Input Voltage Range  
Adjustable Output Voltage Range From  
1.2 V to 16 V  
The TPS6211x is a synchronous PWM converter with  
integrated – and P-channel power MOSFET switches.  
Synchronous rectification is used to increase ef-  
ficiency and to reduce external component count. To  
achieve highest efficiency over a wide load current  
Fixed Output Voltage Options Available in  
3.3 V and 5 V  
Synchronizable to External Clock Signal up to  
1.4 MHz  
range, the converter enters  
a
power-saving,  
pulse-frequency modulation (PFM) mode at light load  
currents. Operating frequency is typically 1 MHz,  
allowing the use of small inductor and capacitor  
values. The device can be synchronized to an exter-  
nal clock signal in the range of 0.8 MHz to 1.4 MHz.  
For low noise operation, the converter can be  
operated in PWM-only mode. In the shutdown mode,  
the current consumption is reduced to less than 2 µA.  
The TPS6211x is available in the 16-pin (RSA) QFN  
package, and operates over a free-air temperature  
range of –40°C to 85°C.  
Up to 1.5-A Output Current  
High Efficiency Over a Wide Load Current  
Range Due to PFM/PWM Operation Mode  
100% Maximum Duty Cycle for Lowest  
Dropout  
20-µA Quiescent Current (Typical)  
Overtemperature and Overcurrent Protected  
Available in 16-Pin QFN Package
