 High-Efficiency Synchronous Step-Down Converter With up to 95% Efficiency " 3.1-V to 17-V Operating Input Voltage Range " 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 to 4-cell Li-ion battery or from a 12-V or 15-V rail. 
 Adjustable Output Voltage Range From 1.2 V to 16 V " Fixed Output Voltage Options Available in " The TPS6211x is a synchronous PWM converter with integrated N-and P-channel power MOSFET switches. Synchronous rectification is used to 
3.3 V and 5 V  increase efficiency and to reduce external component 
 Synchronizable to External Clock Signal up to 1.4 MHz " count. To achieve highest efficiency over a wide load-current range, the converter enters a power-saving, 
 Up to 1.5-A Output Current " pulse-frequency modulation (PFM) mode at light load currents. Operating frequency is typically 1 MHz, 
 High Efficiency Over a Wide Load-Current " allowing the use of small inductor and capacitor 
Range Due to PFM/PWM Operation Mode  values. The device can be synchronized to an 
 100% Maximum Duty Cycle for Lowest Dropout " 20-μA Quiescent Current (Typical) " external 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 
 Overtemperature and Overcurrent Protected " than 2 μA. The TPS6211x is available in the 16-pin 
 Available in 16-Pin QFN Package " (RSA) QFN package, and operates over a free-air temperature range of –40°C to 85°C.
