The TPS62260DDCTG4 is a 2.25MHz Step-down Converter that provides up to 600mA output current from a single Li-ion cell and is ideal for battery-powered applications such as mobile phones and other portable equipment. With a wide input voltage range of 2 to 6V, the device also supports two- and three-cell alkaline batteries, 3.3 and 5V input voltage rails. The TPS62260 operates at 2.25MHz 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 1μA. It allows the use of small inductors and capacitors to achieve a small solution size.
