MAX16133BFM/V+T

Supervisors Overview

The MAX16133BFM/V+T is a high-efficiency, synchronous step-down DC-DC converter manufactured by Analog Devices Inc. (Maxim Integrated). It operates with an input voltage range of 2.7V to 5.5V and delivers up to 3A of output current. The device integrates low RDS(ON) N-channel MOSFETs and features a fixed switching frequency of 2.2MHz. It includes programmable soft-start, cycle-by-cycle current limit, thermal shutdown, and power-good indication. The component is housed in a compact 4mm x 4mm TQFN-16 package and is qualified for automotive applications under AEC-Q100 standards.

Supervisors Feature Summary

• Integrated synchronous rectification with built-in N-channel power switches
• Fixed 2.2MHz switching frequency for small external component size
• Automotive-grade reliability with AEC-Q100 qualification
• Comprehensive protection including thermal shutdown and current limiting

Supervisors Applications

• Point-of-load regulation in automotive infotainment systems
• Power supply for telematics control units
• Voltage regulation for body control modules
• General automotive electronics requiring high efficiency

Supervisors Procurement Notes

Verify the specific suffix 'V+' indicates automotive grade qualification and lead-free status. Confirm the 'T' suffix denotes tape-and-reel packaging. Check for active production status as automotive components may undergo lifecycle changes. Ensure compatibility with your board layout regarding the TQFN-16 thermal pad requirements.

Supervisors Selection Notes

Select this part when a compact, high-frequency solution is needed for 3.3V or 5V rails from a 5V or 12V source. The 2.2MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Consider the thermal performance of the TQFN package if operating near the 3A limit. Verify that the input voltage does not exceed the 5.5V maximum rating.

Supervisors Part Context

This component belongs to the MAX1613x family of synchronous buck converters designed for automotive and industrial applications. It shares architectural similarities with other Maxim integrated switch regulators but is optimized for the specific voltage and current requirements of modern vehicle electronics. The family emphasizes efficiency and small footprint.

Supervisors Replacement Considerations

Check for direct pin-compatible replacements within the MAX1613x series. Verify equivalent electrical parameters such as switching frequency and current capability. Ensure any substitute maintains AEC-Q100 qualification if used in automotive contexts. Consult official cross-reference guides for validated alternatives.
