DESCRIPTION
There are three Buck Converters in the P95020. They are
identical except for their output current ratings.
The two BUCK500 power supplies (BUCK500_0 and
BUCK500_1) each provide 0.75V to 3.70V at up to
500 mA.
The BUCK1000 power supply provides 0.75V to 3.70V at
up to 1000 mA.
All Buck Converters are internally compensated, each
requiring a single input bypass capacitor and an output
filter consisting of one L and one C component.
APPLICATIONS
The primary usage is to power Digital Cores, Application
Processors, and RF Power Amplifiers.
