LM22675QMRE-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM22675QMRE-5.0/NOPB is a fixed-output buck converter from Texas Instruments' SIMPLE SWITCHER family, designed for high-efficiency step-down voltage regulation. It features an integrated power switch capable of delivering up to 1A output current with a fixed 5V output voltage. The device operates at a switching frequency of 500kHz and supports an input voltage range from 4.5V to 42V. Packaged in an 8-SO PowerPAD (VSSOP) with exposed thermal pad, it ensures robust thermal performance. Qualified under AEC-Q100 standards, it functions reliably within an operating temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated high-side N-channel MOSFET switch enables compact design without external driver requirements
• Fixed 5V output option simplifies system design by eliminating external feedback resistor networks
• AEC-Q100 qualification ensures reliability and compliance for automotive electronic applications

Voltage Regulators - DC DC Switching Regulators Applications

• Automotive infotainment and display power distribution systems
• On-board charger (OBC) auxiliary power supplies
• Industrial control module voltage regulation
• Point-of-load conversion for embedded computing hardware

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'QMR' indicates automotive-grade qualification and SOIC package variant. Confirm 'NOPB' denotes lead-free and RoHS compliance status. Ensure the fixed 5.0V output matches the target application requirement, as adjustable variants exist within the same series. Cross-reference the manufacturer datasheet for pinout compatibility and thermal pad soldering guidelines.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5V output is required for automotive or industrial environments. The 1A current limit suits low-to-medium power loads. Consider the 500kHz frequency for balancing component size and efficiency. Evaluate thermal dissipation needs due to the exposed pad package. Compare against other SIMPLE SWITCHER devices if higher current or different input ranges are necessary.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2267x series of SIMPLE SWITCHER regulators, which integrate power switches and control circuitry into a single monolithic IC. The 'Q' prefix typically signifies automotive qualification, while 'MRE' denotes the specific 8-pin SOIC PowerPAD package. It complements other variants like the LM22673 (3A) and LM22676 (3A) for scalable power solutions.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM22675MRE-5.0/NOPB offers identical electrical specifications but lacks automotive qualification. LM22675QMR-ADJ/NOPB provides adjustable output instead of fixed 5V. LM22673QMRE-5.0/NOPB delivers higher 3A current capacity with similar packaging and qualification.
