MAX20012BATJB/V+

Overview

The MAX20012BATJB/V+ is a dual-output, high-efficiency, synchronous step-down controller IC designed for automotive applications. It operates within an input voltage range of 3.0V to 5.5V and supports output voltages starting from 0.50V. The device utilizes a 32-TQFN (5x5) surface-mount package with an exposed pad for thermal management. It functions as a PWM controller PMIC, featuring a supply current of 1.1mA and operating across a temperature range of -40°C to 125°C.

Feature Summary

• Dual-output synchronous step-down architecture for high efficiency
• Automotive-grade reliability with extended temperature range
• Wide input voltage compatibility for low-voltage systems

Applications

• Automotive power distribution units
• Low-voltage DC-DC conversion in vehicle electronics
• Multi-rail power management for infotainment systems

Procurement Notes

Verify the exact suffix 'JB/V+' against the manufacturer's official datasheet to ensure correct pinout and thermal pad configuration. Confirm that the component meets specific automotive qualification standards required by your application. Check for RoHS compliance documentation provided by Analog Devices. Ensure the TQFN package dimensions match your PCB footprint design constraints before ordering.

Selection Notes

Select this component when designing multi-output buck converters requiring automotive-grade performance. It is suitable for applications needing independent regulation of two outputs from a single controller. Consider the 32-TQFN package size for space-constrained designs. Evaluate thermal dissipation requirements due to the exposed pad structure. Compare against single-channel alternatives if only one regulated rail is necessary.

Part Context

This part belongs to the MAX20012B series of automotive low-voltage controllers. It is manufactured by Analog Devices Inc./Maxim Integrated. The device is distinct from non-automotive variants and shares functional similarities with other members of the MAX200xx family but offers specific dual-channel capabilities optimized for automotive environments.

Replacement Considerations

Direct substitutes include the MAX20096ATJ/VY+, which offers similar LED driver and DC-DC controller functionality in a 32-TQFN package. Verify pin-to-pin compatibility and electrical specifications before swapping.
