FEATURES  
DESCRIPTION  
The TPS6205x devices are a family of high-efficiency  
2
High-Efficiency Synchronous Step-Down  
Converter With up to 95% Efficiency  
synchronous step-down dc/dc converters ideally  
suited for systems powered from a 1-cell or 2-cell Li-  
Ion battery or from a 3-cell to 5-cell NiCd, NiMH, or  
alkaline battery.  
12-µA Quiescent Current (Typ)  
2.7-V to 10-V Operating Input Voltage Range  
Adjustable Output Voltage Range From 0.7 V  
to 6 V  
The TPS62050 is a synchronous PWM converter with  
integrated N-channel and P-channel power MOSFET  
switches.  
Synchronous  
rectification  
increases  
Fixed Output Voltage Options Available in  
1.5 V, 1.8 V, and 3.3 V  
efficiency and reduces external component count. To  
achieve highest efficiency over a wide load current  
range, the converter enters a power-saving pulse-  
frequency modulation (PFM) mode at light load  
currents. Operating frequency is typically 850 kHz,  
allowing the use of small inductor and capacitor  
values. The device can be synchronized to an  
external clock signal in the range of 600 kHz to 1.2  
MHz. For low noise operation, the converter can be  
programmed into forced-fixed frequency in PWM  
mode. In shutdown mode, the current consumption is  
reduced to less than 2 µA. The TPS6205x is  
available in the 10-pin (DGS) micro-small outline  
package (MSOP) and operates over an free air  
temperature range of –40°C to 85°C.  
Synchronizable to External Clock Signal up to  
1.2 MHz  
High Efficiency Over a Wide Load Current  
Range in Power-Save Mode  
100% Maximum Duty Cycle for Lowest  
Dropout  
Low Noise Operation in Forced Fixed  
Frequency PWM Operation Mode  
Internal Softstart  
Overtemperature and Overcurrent Protected  
Available in 10-Pin Microsmall Outline  
Package MSOP
