MAX16930ATLR/V+

DC DC Switching Controllers Overview

The MAX16930ATLR/V+ is a dual buck switching controller with an integrated preboost stage, designed for high-efficiency power conversion in automotive and industrial applications. It operates from a wide input voltage range up to 36V and supports output currents of up to 20A per channel. The device features a fixed 2MHz switching frequency, enabling the use of small external components. It includes comprehensive protection features such as overcurrent, overvoltage, and thermal shutdown, ensuring reliable operation under demanding conditions.

DC DC Switching Controllers Feature Summary

• Integrates a preboost stage to maintain regulation during low input voltage conditions
• Dual independent buck channels with adjustable output voltages
• Fixed 2MHz switching frequency for compact passive component sizing
• Comprehensive protection mechanisms including overcurrent and thermal shutdown

DC DC Switching Controllers Applications

• Automotive infotainment systems
• Industrial motor control circuits
• High-current point-of-load regulation

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'ATLR/V+' against the manufacturer's official datasheet to ensure correct package type (TQFN-40) and temperature grade. Confirm that the preboost functionality aligns with your system's input voltage profile. Check for obsolescence status or lifecycle notices directly from Analog Devices before finalizing procurement plans.

DC DC Switching Controllers Selection Notes

Select this component when dual isolated outputs are required from a single high-voltage source. The integrated preboost simplifies design for applications where input voltage may dip below output requirements. Ensure adequate thermal management due to high current capabilities. Compare with single-channel alternatives if only one regulated output is needed to optimize board space and cost.

DC DC Switching Controllers Part Context

This part belongs to the MAX169xx family of high-performance DC-DC controllers from Maxim Integrated, now part of Analog Devices. These devices are engineered for robust performance in noisy environments typical of automotive and industrial sectors. The MAX16930 specifically addresses the need for multi-rail power distribution with minimal component count.

DC DC Switching Controllers Replacement Considerations

Check for direct pin-to-pin replacements within the MAX169xx series, such as the MAX16933, which offers similar dual-buck architecture but may differ in quiescent current specifications. Verify compatibility with existing PCB layouts and control loop compensation networks before substitution.
