LM25011Q1MYX/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM25011Q1MYX/NOPB is an automotive-grade constant-on-time (COT) buck switching regulator designed for high-voltage input applications. It supports an input voltage range of 6 V to 42 V and delivers up to 2 A of output current. The device features adjustable output voltages from 2.51 V to 40 V with a fixed internal switching frequency of 2.25 MHz. It operates within a temperature range of -40°C to +125°C and is housed in a 10-pin HVSSOP package with an exposed pad.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for reliability in vehicle environments.
• Constant-on-time control architecture enables stable operation across wide input voltage ranges without requiring external compensation networks.
• Integrated adjustable current limit protects against short circuits and overloads while maintaining precise regulation.

Voltage Regulators - DC DC Switching Regulators Applications

• Automotive infotainment systems
• Body control modules
• High-side power distribution units

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix NOPB indicates lead-free composition and RoHS compliance. Confirm the Q1 designation ensures automotive grade qualification. Check the MYX suffix for tape-and-reel packaging specifications. Ensure the HVSSOP-10 package matches your PCB footprint requirements. Validate the operating temperature range meets your specific environmental constraints.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing for automotive applications requiring wide input voltage tolerance and high efficiency. The fixed 2.25 MHz frequency allows for smaller passive components compared to lower-frequency regulators. Ensure the thermal design accommodates the power dissipation in the HVSSOP package. Verify that the load current does not exceed the 2 A continuous rating under all operating conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM25011 family of synchronous buck converters. It shares architectural similarities with the non-automotive LM25011 but includes enhanced testing and documentation for automotive reliability. It serves as a drop-in replacement for other 42V input buck regulators in automotive designs where AEC-Q100 certification is mandatory.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM25011AMYE is the commercial grade equivalent with identical electrical performance but lacks automotive qualification. LM25011Q1MY is the non-reel version of the same automotive device. Verify pinout compatibility before substitution.
