MAX20406: Automotive, 36V, 4A/5A/6A fully-integrated synchronous buck converter

NPI21 Sep 2022

It is capable of 2 MHz operation due to its 33 ns on-time to ensure it stays in 2 MHz operation even during input voltage transients to keep the solution size small and enable low EMI. The quiescent current is only 10 μA to preserve the battery life of always-on automotive systems.

Key features and benefits

Power savings: programmable current with closed-loop regulation saves > 50% of power
Flexibility in design: half bridges (channels) are completely independent
Space savings: Integrated Current Sensing (ICS) saves > 30% PCB space and simplifies the layout
