RBB10-2.0-EVM-1
Quick Start Guide
1) Connect Sense to the required potential.
The Sense input is via R3 directly at the power module output. To compensate for ohmic losses of the filter, desolder the R3 resistor
and move it to the position of R4.
If you want to sense directly on the load, desolder R3 and connect the middle pin of Con 2 to the positive potential of the load with a
separate connection.
2) If a different output voltage is required, fit R5 or R6.
3) Connect Con1 to a DC power supply and check output voltage.
4) Connect Con2 to the load.
5) Enable the device on Con3.
The converter is normally on. You can disable the converter by pulling the Enable pin to GND with a switch, open collector driver or logic
input. R1 or R2 can be used to change the default function from normally on to normally off.
6) Modes:
The RBB10-2.0 has the possibility to work in two regulation modes:
6.1) 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.
6.2) 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 pin on Con4 to GND or solder a 0Ω
resistor a position R7 to enter this mode.
