MAX20406AFOB/VY+

MAX20406AFOB/VY+ is an automotive-grade synchronous buck regulator IC from Maxim Integrated (now Analog Devices). It integrates the high- and low-side MOSFETs and the control logic to efficiently convert a higher input voltage to a lower regulated output. Key ideas:
- Wide input range, adjustable output, and programmable switching frequency
- Enable/shutdown control and protections (overcurrent/short-circuit, overtemperature, UVLO/OVP)
- Suitable for automotive/industrial power management and supplying core rails for microcontrollers, FPGAs, DSPs, and similar loads
- AFOB/VY+ denote specific package variants and grading (temperature/lead-free/package code)
Note: exact specs (input range, output current capability, pinout, layouts) vary by variant. For precise electrical characteristics, recommended layouts, and packaging details, consult the latest MAX20406AFOB/VY+ datasheet and packaging documentation.
