LM25575QMH/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM25575QMH/NOPB is an automotive-grade, wide-input voltage synchronous buck switching regulator from Texas Instruments. It supports input voltages from 6 V to 42 V and delivers up to 1.5 A of output current. The device integrates a high-side N-channel MOSFET and features adjustable switching frequencies between 50 kHz and 1 MHz. It operates within a temperature range of -40°C to +125°C and is housed in a 16-pin PowerTSSOP package with an exposed pad for thermal management.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated synchronous rectification using internal high-side and low-side N-channel MOSFETs for improved efficiency.
• Wide input voltage range capability supporting 6 V to 42 V operation for flexible system design.
• Adjustable switching frequency allows optimization for external component size and transient response.
• Automotive qualification compliant with AEC-Q100 standards for reliability in harsh environments.

Voltage Regulators - DC DC Switching Regulators Applications

• Automotive infotainment systems requiring stable power delivery.
• Body control modules and lighting applications in vehicles.
• Industrial DC-DC conversion for 24 V or 48 V bus architectures.
• General-purpose step-down regulation in automotive electronics.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'QMH' confirms the Q100 automotive grade and HTSSOP-EP-16 package variant. Confirm 'NOPB' indicates lead-free and RoHS compliance. Ensure the source document explicitly lists this exact part number as available; do not assume availability based on family members. Check for any recent PCN updates affecting marking or packaging.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing for automotive environments requiring AEC-Q100 certification. It is suitable for applications needing a single output up to 1.5 A from a 6 V to 42 V input. Consider the 16-pin PowerTSSOP package for thermal performance. Compare against LM25576 if higher current (3 A) is required, or LM5575 if input voltages exceed 42 V.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the SIMPLE SWITCHER family of integrated power modules. It simplifies design by combining the controller, drivers, and power switches into a single IC. The LM25575 series is distinct from the LM2575 due to its synchronous architecture and wider input voltage range, targeting modern automotive and industrial applications.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Publicly confirmed substitutes include LM25575MH/NOPB (non-automotive grade) and LM25575MHX/NOPB (tape and reel). Direct cross-replacement requires verifying that the non-Q version meets the application's reliability requirements. No other TI models share identical pinouts and electrical specs without modification.
