It supports • Excellent AC and Transient Load Regulation up to 500mA output current and allows the use of tiny • High PSRR (up to 90dB) and low cost chip inductors and capacitors. • Small External Output Filter Components 1 μH/ With a wide input voltage range of 2.05V to 6V the 4.7 μF device supports applications powered by Li-Ion batteries with extended voltage range. The minimum • VIN range from 2.05V to 6V input voltage of 2.05V allows as well the operation • Optimized Power Save Mode For Low Output from Li-primary or two alkaline batteries. Different Ripple Voltage fixed output voltage versions are available from 1.2V • Forced PWM Mode Operation to 2.5V. • Typ. 22 μA Quiescent Current The TPS6223X series features switch frequency up • 100% Duty Cycle for Lowest Dropout to 3.8MHz. At medium to heavy loads, the converter operates in PWM mode and automatically enters • Small 1 × 1.5 × 0.6mm3 SON Package Power Save Mode operation at light load currents to • 12 mm2 Minimum Solution Size maintain high efficiency over the entire load current • Supports 0.6 mm Maximum Solution Height range. • Soft Start with typ. 100 μs Start Up Time Because of its excellent PSRR and AC load regulation performance, the device is also suitable to APPLICATIONS replace linear regulators to obtain better power • LDO Replacement conversion efficiency. • Portable Audio, Portable Media The Power Save Mode in TPS6223X reduces the • Cell Phones quiescent current consumption down to 22 μA during light load operation. It is optimized to achieve very • Low Power Wireless low output voltage ripple even with small external • Low Power DSP Core Supply component and features excellent ac load regulation. • Digital Cameras For very noise sensitive applications, the device can be forced to PWM Mode operation over the entire load range by pulling the MODE pin high. In the shutdown mode, the current consumption is reduced to less than 1 μA. The TPS6223X is available in a 1 × 1.5mm2 6 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.
