The TPS6223x device family is a high-frequency, synchronous, step-down DC – DC converter optimized for battery powered portable applications. 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.
Because of its excellent power supply rejection ratio (PSRR) and AC load regulation performance, the device is also suitable to replace linear regulators to obtain better power conversion efficiency.
The power-save mode in TPS6223x reduces the quiescent current consumption down to 22 µA during light load operation. It is optimized to achieve very low output voltage ripple even with small external component and features excellent AC load regulation.
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 operates over a junction temperature range of –40°C to 125°C. It is available in a 1 mm × 1.5 mm × 0.6 mm 6-pin SON package.
