LM25019SDX/NOPB, classified as PMIC - Voltage Regulators - DC DC Switching Regulators, is the next generation of synchronous DC/DC LCD controllers. It integrates boost, buck and flyback converters into one device to deliver a high-efficiency power solution with low output voltages up to 72V. This device includes a wide selection of power sources, including: low-side, automotive-grade integrated gate drivers, wide voltage range of input voltage, monitored transistor temperature and an adjustable switching frequency.

This device can be used for a wide range of applications such as AC-DC, DC-DC and POL converters, voltage regulators, buck, boost and flyback converters, remote sensing, and multi-port addressable LVDS I/O. Its high input voltage range of up to 72V makes it ideal for automotive, communications, industrial and automotive applications. It is capable of generating up to 8A of continuous output current, and its integrated flyback converter can be used to create up to 24V of regulated output voltage.

The LM25019SDX/NOPB was designed to simplify the design process for DC/DC converters by simplifying the circuit layout and providing robust protections. It features a multi-channel low-side gate driver, designed to spread the gate load equally across all channels to reduce switching noise and simplify the circuit layout. The LM25019SDX/NOPB also features an innovative over-current protection circuit which senses the current waveform and acts before an overload becomes critical, thus preventing stress on sensitive system components.

For efficient operation, the LM25019SDX/NOPB includes an active voltage controller which provides constant output voltage regulation and power sequencing. This active voltage controller is capable of maintaining the utmost accuracy while operating in demanding conditions. An adjustable switching frequency, over-current protection, under-voltage lockout, overvoltage protection and thermal shutdown provide additional protection for the system.

The LM25019SDX/NOPB\'s small footprint and the integration of the boost, buck and flyback circuitry into one device significantly reduce the part count and design complexity of the design, while still providing superior power efficiency, reliability, and protection. It has been designed to provide the highest level of performance in its class, with current ratings of up to 8A, output voltage ratings up to 72V and switching frequencies up to 1MHz. It is also extremely energy efficient, with efficiency ratings up to 95%.

The LM25019SDX/NOPB is a great choice for system designers looking for a highly-efficient and highly-reliable power solution for their products. It is a simple solution that integrates all the essential components needed for power conversion into a single device, making it the perfect fit for many applications. Its high input voltage range, robust protective features and high current output makes it a perfect choice for a wide range of power applications.
