2.25 MHz 600 mA Step Down Converter in 2x2SON/TSOT-23 Package
and
other
portable
With an wide input voltage range of 2 V to 6 V, the
device supports applications powered by Li-Ion
batteries with extended voltage range, two and three
cell alkaline batteries, 3.3 V and 5 V input voltage
rails.
The TPS62260 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 PWM mode by
pulling the MODE pin high. In the shutdown mode,
the current consumption is reduced to less than 1
μ
A.
TPS62260 allows the use of small inductors and
capacitors to achieve a small solution size.
The TPS62260 is available in a very small 2

2 6 pin
SON and TSOT-23 5 pin package.
