POWER SECTION

SENSE RESISTOR

It is important, for this component, to keep in mind three factor: it must be able to dissipate high power. Again

its variation with the temperature must be small and the precision must be high to ensure high precision with the

ST voltage droop function.

INPUT CAPACITOR

For this components can be useful control the temperature coefficient and the equivalent serie resistor and the

voltage rated.

OUTPUT CAPACITOR

For this components can be useful control the temperature coefficient and the equivalent series resistor and the

voltage rated.

INDUCTOR

For the inductor important factors are the saturation current and the equivalent series resistor (for the efficiency

improvements)

POWER MOS

Note N.M.=Not Mounted.

For the MOSFET choose is important to know the input voltage and output voltage. The MOSFET must able
