Switching at 2.2 MHz keeps the inductor and output cap small — the 10-TDFN (3x3 mm) exposed-pad package sheds heat into the PCB copper, so a 2A load at 125°C ambient is viable with proper layout. ## What the 2.2 MHz switching frequency buys you At 2.2 MHz the fundamental ripple sits above the AM broadcast band and most sensor bandwidths — you can get away with a 1 µH inductor and 10 µF output cap and still hold ripple under 20 mVpp at 2A. The trade-off is switching loss: at high line (6V in, 1.8V out) the duty cycle is 30%, and the internal FETs' gate charge times frequency eats about 5% of the output power. That is fine for a 2A rail; it would be painful at 10A. ## AEC-Q100 Grade 1 temperature and the exposed pad The 10-TDFN exposed pad (3x3 mm) is the primary thermal path — the datasheet recommends a 4-via thermal land on the bottom layer. Without it the RθJA climbs past 60°C/W and the 2A output derates above 85°C ambient.","metaTitle":"MAX20073ATBA/V+ Buck Converter, 2A, 2.2MHz, AEC-Q100","metaDescription":"Analog Devices MAX20073ATBA/V+ automotive step-down regulator, 2A output, 2.2MHz switching, -40 to 125°C, 10-TDFN.
