They • VIN Range from 2.9 V to 6 V provide up to 2-A output current. • Up to 97% Efficiency With an input voltage range of 2.9 V to 6 V, the • Power Save Mode / 3-MHz Fixed PWM Mode device is a perfect fit for power conversion from a 5-V • Power Good Output or 3.3-V system supply rail. The TPS6206x operates at 3-MHz fixed frequency and enters power save • Output Voltage Accuracy in PWM Mode ±1.5% mode operation at light load currents to maintain high • Output Capacitor Discharge Function efficiency over the entire load current range. The • Typical 18 µA Quiescent Current power save mode is optimized for low output voltage ripple. For low noise applications, TPS62065 can be • 100% Duty Cycle for Lowest Dropout forced into fixed frequency PWM mode by pulling the • Voltage Positioning MODE pin high. TPS62067 provides an open drain • Clock Dithering power good output. • Supports Maximum 1-mm Height Solutions In the shutdown mode, the current consumption is • Available in a 2 mm x 2 mm x 0.75 mm WSON reduced to less than 1 µA and an internal circuit discharges the output capacitor. 2 Applications TPS6206x family is optimized for operation with a tiny • Point of Load (POL) 1 µH inductor and a small 10-µF output capacitor to achieve smallest solution size and high regulation • Notebooks, Pocket PCs performance. • Portable Media Players The TPS6206x operates over a free air temperature • DSP Supply range of –40°C to 85°C. It is available in a small 2- mm × 2-mm × 0.75-mm 8-pin WSON package.
