Frequently Asked Questions
What makes the LM25119QPSQ/NOPB suitable for automotive applications?
The LM25119QPSQ/NOPB carries AEC-Q100 automotive qualification and operates over a -40°C to 125°C temperature range, meeting the stringent reliability, EMC, and temperature requirements of automotive electronic control units. Its 4.5V to 42V input range also covers the full range of automotive battery conditions including cold-crank and load-dump transients.
How many regulated outputs does the LM25119QPSQ/NOPB provide?
The LM25119QPSQ/NOPB is a dual-channel controller, providing two independent synchronous buck converter outputs. Each channel operates independently with its own current sensing, error amplifier, and gate drive, enabling a single IC to generate two different supply voltages from the same input bus.
What is the minimum programmable output voltage of the LM25119QPSQ/NOPB?
The LM25119QPSQ/NOPB can be programmed to produce output voltages as low as 0.8V using an external resistor divider network. This minimum output voltage covers the core supply requirements of advanced automotive processors, FPGAs, and memory devices used in modern ADAS and infotainment systems.
What package does the LM25119QPSQ/NOPB use?
The LM25119QPSQ/NOPB is housed in a 32-pin WQFN (Wireless Quad Flat No-Lead) package with an exposed thermal pad. The no-lead package minimizes parasitic inductance and provides excellent thermal dissipation through the PCB, which is important for high-efficiency dual-channel buck converters in space-constrained automotive ECUs.
