TPS62233DRYT Datasheet PDF - TI

●The TPS62233DRYT is a synchronous Step-down DC-to-DC Converter supports up to 500mA output current and allows the use of tiny chip inductors and capacitors. With a wide input voltage range of 2.05 to 6V, the device supports applications powered by li-ion batteries with extended voltage range. The minimum input voltage of 2.05V allows as well the operation from Li-primary or two alkaline batteries. Different fixed output voltage versions are available from 1 to 3.3V. The TPS6223x series features switch frequency up to 3.8MHz. 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.
