Description
Introduction
The MAX16974/MAX16975/MAX16976 DC-DC converters are standard buck controllers designed for automotive applications. These controllers feature an integrated high-side N-channel FET and an external free-wheeling diode. Proper PCB layout of the IC, along with all the external components, is critical for reliable operation and for minimizing EMI emissions. This application note highlights some of the key points of the circuits for optimizing the layout. Figure 1 shows the typical application circuit of these high-performance converters.
