device
is
a
high
efficiency
With an 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,
3.3-V and 5-V input voltage rails.
The TPS62240 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.
TPS62240 allows the use of small inductors and
capacitors to achieve a small solution size.
The TPS62240 is available in a 5-pin TSOT23 and
6-pin 2mm
×
2mm SON package.
