APPLICATIONS
switching frequency and enters a Power Save Mode
Portable Handheld
operation at light load currents to maintain a high
WLAN
efficiency over the entire load current range.
Low Power DSP Supply
The Power Save Mode is optimized for low output
voltage ripple. For low noise applications, the device
POL
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
A.
The TPS62590 allows the use of small inductors and
capacitors to achieve a small solution size.
The TPS62590 is available in a 2-mm
× 2-mm 6-pin
QFN package.
