The TPS65705x devices are small power management units targeted for embedded camera
module or other portable low-power consumer-end equipments. The device contains two highly
efficient step-down converters, a low dropout linear regulator, and additional supporting
functions. The 2.25-MHz step-down converter enters a low-power mode at light load for maximum
efficiency across the widest possible range of load currents. For low-noise applications, the
device can be forced into fixed-frequency PWM mode using the MODE pin. The device allows the use of
small inductors and capacitors to achieve a small sized solution. The TPS65705x provides an output
current of up to
400 mA on both DC-DC converters and integrates one 200-mA LDO with different output settings.
The LDO operates with an input voltage range from 1.7 V to 6 V, thus allowing it to be supplied
from the output of the step-down converter or directly from the system voltage.
The TPS65705x comes in a small 16-pin wafer chip scale package (WCSP) with 0.5-mm ball
