3 Description
The TPS62560 device is a high efficiency
synchronous step down converter, optimized for
battery powered portable applications. It provides up
to 600-mA output current from batteries, such as
single Li-Ion or other common chemistry AA and AAA
cells.
With an input voltage range of 2.5 V to 5.5 V, the
device is targeted to power a large variety of portable
handheld equipment or POL applications.
The TPS62560 family operates at 2.25-MHz fixed
switching frequency and enters a Power Save Mode
operation at light load currents to maintain a 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 μA.
The TPS62560 allows the use of small inductors and
capacitors to achieve a small solution size.
TPS62560 and TPS62562 are available in a 2-mm ×
2-mm, 6-pin SON package, whereas the TPS62561 is
available in a 5-pin SOT package.
