The TPS6226x device is a highly efficient synchronous step-down DC/DC converter. The
TPS6226x provides up to 600-mA output current from a single Li-Ion cell, and is ideal for
battery-powered applications such as 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 batteries, 3.3-V and 5-V input voltage rails.
The TPS6226x 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 range.
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 the shutdown mode, the current consumption is reduced to less than 1
µA. The TPS6226x allows the use of small inductors and capacitors to achieve a small solution
The TPS6226x operates over a free air temperature range of 40°C to 85°C. It is available
in a 5-pin SOT and a 6-pin 2-mm × 2-mm WSON package.
