Automotive Buck-Boost Power Solution Reference Design


Design files


PMP10170 provides a constant output voltage of 5.0V @ 500mA from an wide input voltage range of 4.0V up to 39.0V. It is working with a fixed switching frequency of 380 kHz but provides also the possibility to modulate the switching frequency to reduce the EMI.
