The pulse converters have much higher efficiency than linear regulators. But require additional external components. Framed incorrectly can be a source of interference
Schedule przestawiający the dependence of the efficiency of the system from current.
A diagram showing the use of the system as a stabilizer of 5V.
The method of selection of coils and capacitors, have been described in detail in the documentation.
Resistors therefore, we believe that in the formula:
R1 = R2 x (Vout - Vfb) / Vfb
Vout - the output voltage that we want to achieve
Vfb = 0.8 V
R2 is typical recommended value is 20 ohms
For Vout = 5V, the value of R1 will be equal to 105 ohms.
When designing the printed circuit BOARD should pay particular attention to the ground wire in the system. Paths should be thick. Capacitors as close as possible to the contacts of the Converter. In the documentation the manufacturer recommends how you want to arrange elements.
Sugerowny PCB design.
