Schematic
Description
IC1 is the RBB10-2.0 power module.
C1,C2,L1,L2,L3,L7,C5,C6 give the possibility to try different input EMC filters. The populated filter is designed to meet EN55032 class B has
C1, L7 and C6 fitted.
C7,C8,L4,L5,L6,L8,C3,C4 give the possibility to try different output EMC filters. The populated filter is designed to meet EN55032 class B has
L8 and C3 fitted.
R1 and R2 give the possibility to preset the Enable pin in other configurations.
These resistors are not populated. The default for IC1 is always on.
If R2 is fitted, then the enable is normally on, pull down to ground to turn off. If R1 is fitted, the enable is normally off, pull up to Vin to turn on.
Refer to the datasheet of IC1 for more information.
C9 is not populated on this board.
R3 is a populated 0Ω resistor for output voltage sensing directly at the module output. If the output sense input is required at the point of load,
unsolder R3 and connect the Sense pin to the load.
R4 gives the possibility to compensate the output voltage for any voltage drop through the EMC filter by unsoldering R3 and soldering it at the
position of R4.
R7 and R8 are not populated on this Board.
R5 and R6 give the possibility to trim the output voltage between 1.0V and 5.5V (see calculations and trim table below). Fit only R5 or R6.
