It supports up to 500-mA output current and allows the use of tiny and low-cost chip inductors and capacitors.
With a wide input voltage range of 2.
05 V to 6 V, the device supports applications powered by Li-Ion batteries with extended voltage range.
The minimum input voltage of 2.
05 V allows as well the operation from Li-primary or two alkaline batteries.
Different fixed output voltage versions are available from 1.
0 V to 3.
3 V.
The TPS6223x series features switch frequency up to 3.
8 MHz.
At medium to heavy loads, the converter operates in pulse width modulation (PWM) mode and automatically enters power-save mode operation at light load currents to maintain high efficiency over the entire load current range.
