They • Up to 97% Efficiency provide up to 2.0A output current. • Power Save Mode / 3MHz Fixed PWM Mode With an input voltage range of 3.0V to 6V the device • Power Good Output is a perfect fit for power conversion from a 5V or 3.3V • Output Voltage Accuracy in PWM Mode ±1.5% system supply rail. The TPS6206x operates at 3MHz • Output Capacitor Discharge Function fixed frequency and enters Power Save Mode operation at light load currents to maintain high • Typical 18 µA Quiescent Current efficiency over the entire load current range. The • 100% Duty Cycle for Lowest Dropout Power Save Mode is optimized for low output voltage • Voltage Positioning ripple. For low noise applications, TPS62065 can be forced into fixed frequency PWM mode by pulling the • Clock Dithering MODE pin high. TPS62067 provides an open drain • Supports Maximum 1mm Height Solutions power good output. • Available in a 2x2x0.75mm SON In the shutdown mode, the current consumption is reduced to less than 1µA and an internal circuit APPLICATIONS discharges the output capacitor. • POL TPS6206x family is optimized for operation with a tiny • Notebooks, Pocket PCs 1.0µH inductor and a small 10µF output capacitor to • Portable Media Players achieve smallest solution size and high regulation • DSP Supply performance. The TPS6206X is available in a small 2x2x0.75mm 8-pin SON package. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 PowerPAD is a trademark of Texas Instruments.
