LM25180QNGURQ1

Voltage Regulators - DC DC Switching Regulators Overview

The LM25180QNGURQ1 is an automotive-grade primary-side regulated (PSR) flyback DC/DC converter from Texas Instruments. It integrates a 65-V, 1.5-A power MOSFET and supports an input voltage range of 4.5 V to 42 V. The device operates with a switching frequency between 12 kHz and 350 kHz and delivers up to 1.5 A output current. It features adjustable output voltage, shutdown capability, and functions within a junction temperature range of -40°C to +150°C. Packaged in an 8-WSON (4x4 mm) surface-mount case, it includes internal soft-start and protection mechanisms.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the Q1 suffix confirms AEC-Q100 automotive qualification. Confirm the NGUR package variant matches WSON-8 requirements. Check datasheet for specific thermal pad soldering guidelines. Ensure component availability aligns with production timelines. Validate that the fixed or adjustable output configuration meets system specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when high integration and cost-effective isolation are required. The integrated MOSFET reduces external component count compared to controller-based solutions. Consider the 65-V drain rating for standard 12-V or 24-V automotive bus applications. Evaluate thermal performance given the small WSON footprint. Compare against LM25183 or LM25184 if higher current capacity is needed.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2518x family of PSR flyback converters. It shares architectural similarities with the LM25183 and LM25184 but offers lower current handling. The family targets applications requiring simple, robust isolated power solutions without feedback loop compensation complexity.
