The device 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 can be powered by a preregulated voltage rail or Li-Ion batteries with extended voltage range.
Two different fixed-output voltage versions are available at 1.
5 V and 1.
8 V.
The TPS6223x-Q1 series features switch frequency up to 3.
8 MHz.
At medium to heavy loads, the converter operates in PWM mode and automatically enters Power Save Mode operation at light load currents to maintain high efficiency over the entire load current range.
Because of its excellent PSRR and AC load regulation performance, the device is also suitable to replace ...
