The TPS6224x device is a highly efficient synchronous step-down DC-DC converter. The
device provides up to 300-mA output current from a single Li-Ion cell and is ideal for battery
powered portable applications like mobile phones and other portable equipment.
With an wide input voltage range of 2 V to 6 V, the device also supports two- and
three-cell alkaline, 3.3-V and 5-V input voltage rails.
The TPS6224x operates at 2.25-MHz fixed switching frequency and enters power save mode
operation at light load currents to maintain high efficiency over the entire load current
The power save mode is optimized for low output voltage ripple. For low-noise
applications, the device can be forced into fixed-frequency pulse width modulation (PWM) mode by
pulling the MODE pin high. In shutdown mode, the current consumption is reduced to less than 1 µA.
The TPS6224x allows the use of small inductors and capacitors to achieve a small solution
The TPS6224x operates over a free-air temperature range of 40°C to 85°C. The device is
available in a 5-pin SOT and a 6-pin 2-mm × 2-mm WSON package.
