This reference design is an EMI and thermally optimized synchronous buck converter for automotive applications. The circuit is powered from the nominal 12-V battery to provide an output voltage of 3.3 V at 8 A. The design uses a synchronous buck controller operating at a switching frequency of 440 kHz. Forced pulse width modulation or diode emulation mode is jumper selectable. Frequency dithering is used to improve the EMI performance.
