| FEATURES | DESCRIPTION |
| 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. |
