Notes:
Note6: The RBB10 has the possibility to work in two regulation modes:
Powersave Mode (standard): This mode is the best for use at low loads to reduce power consumption and extend battery life.
In this mode the internal power consumption is reduced by using burst mode for loads under 350mA and PWM for loads above 350mA.
The drawback is a 1-3 % higher output voltage at low load than full load.
Fixed PWM mode: In PWM mode the device accurately regulates the output voltage independently of the load current. The drawback
is a higher internal power consumption and shorter battery life at lower loads. Pull down the Mode pad to GND to enter this mode.
