MAX20012BATJH/VY+T

Overview

The MAX20012BATJH/VY+T is a dual-output synchronous buck switching controller designed for automotive applications, manufactured by Analog Devices Inc./Maxim Integrated. It operates within an input voltage range of 4.5V to 36V and delivers two independent regulated outputs. The device features a fixed 2.2MHz PWM frequency to enhance noise immunity. It achieves ±2% output error across load, line, and temperature variations. The IC integrates overcurrent, overvoltage, and thermal shutdown protections to meet AEC-Q100 Grade 1 requirements.

Feature Summary

• Dual-output synchronous buck architecture
• Automotive-grade reliability (AEC-Q100 Grade 1)
• Integrated protection mechanisms including overcurrent, overvoltage, and thermal shutdown
• Fixed 2.2MHz PWM operation for improved noise immunity

Applications

• Automotive infotainment systems
