Frequently Asked Questions
What is the input voltage range and integrated MOSFET rating of the LM25180QNGUTQ1?
The LM25180QNGUTQ1 accepts input voltages from 4.5V to 42V with a nominal 24V operation. The integrated power MOSFET is rated at 65V and 1.5A, allowing the device to handle typical automotive battery and 24V industrial bus voltage variations without an external switch transistor.
Does the LM25180QNGUTQ1 require an optocoupler for output regulation?
No, the LM25180QNGUTQ1 uses primary-side regulation (PSR) with current-mode resonant control, eliminating the need for an optocoupler or secondary-side feedback components. This simplifies the flyback converter design, reduces the BOM count, and improves reliability in cost-sensitive automotive and industrial applications.
What package does the LM25180QNGUTQ1 use and what is its operating temperature range?
The device is housed in an 8-pin WSON (Small Outline No-lead) package suitable for compact PCB layouts. It is rated for an operating temperature range of -40°C to 150°C junction temperature, meeting AEC-Q100 automotive qualification requirements for high-temperature under-hood and other harsh environment applications.
Is the LM25180QNGUTQ1 suitable for automotive applications?
Yes, the LM25180QNGUTQ1 is AEC-Q100 automotive-qualified with the Q1 suffix, operating reliably from -40°C to 150°C. It is designed for ADAS sensors, body control modules, infotainment power supplies, and other automotive 12V/24V bus systems requiring isolated DC-DC conversion with minimal external components.
What control topology does the LM25180QNGUTQ1 use and why does it matter?
The LM25180QNGUTQ1 employs current-mode resonant control in a flyback topology, which improves efficiency by reducing switching losses compared to conventional hard-switching regulators. This control method also provides inherent short-circuit protection and simplifies compensation, making the design more robust across wide input and load ranges from 4.5V to 42V input.
