Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM5180NGUR

LM5180NGUR

Voltage Regulators - DC DC Switching Regulators Overview

The LM5180NGUR is a primary-side regulated (PSR) flyback DC/DC converter manufactured by Texas Instruments. It integrates a 100-V, 1.5-A power MOSFET and supports an input voltage range up to 70 V. The device operates in an 8-WSON package with a maximum switching frequency of 350 kHz. It features adjustable UVLO thresholds at 1.5 V for on and 1.45 V for off, with a maximum duty cycle of 82%. The operating temperature range spans from -40°C to 150°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrates a high-voltage power MOSFET to minimize external component count
Provides primary-side regulation to eliminate optocouplers and transformers
Supports pre-bias start-up capabilities for safe initialization
Includes adjustable under-voltage lockout and enable functions

Voltage Regulators - DC DC Switching Regulators Applications

Isolated bias power supplies
IGBT gate drive power sources for BDC and BLDC motor drives

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix NGUR against the manufacturer's official datasheet to confirm the tape-and-reel packaging configuration. Ensure the order quantity aligns with standard reel sizes defined in the production documentation. Cross-reference the part number with the latest revision history to validate component specifications before procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component for designs requiring wide input voltage ranges and isolated outputs without feedback isolation components. The integrated switch simplifies layout compared to discrete solutions. Consider the thermal performance within the WSON package when determining heat dissipation requirements for the target application environment.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM5180 family of PSR flyback converters. It shares functional similarities with the LM5180-Q1 automotive-grade variant and the LM25180 series, which offers lower voltage ratings. The LM5181 serves as a related alternative with different current capabilities. These parts address diverse power management needs across industrial and automotive sectors.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM5180-Q1: Automotive-grade version with identical electrical characteristics. LM25180: Lower input voltage rating variant. LM5181: Alternative with different output current specifications.
