The L4973D3.3-013TR is a DC/DC switching regulator specifically designed for applications such as laptops, home appliances, automobiles and other electronic products. It is a type of stepdown regulator, and is commonly found within the category of PMIC (Power Management Integrated Circuit) voltage regulators. The device is able to deliver both regulated and adjustable output voltage, while also featuring optimized energy efficiency.

The L4973D3.3-013TR is a synchronous stepdown regulator, which means that it adjusts its output voltage, based on the input voltage. This is done by a set of internal switches that oscillate and alternate between the input and output lines. In this way, only a portion of the input voltage passes through to the output voltage. By utilizing this method, the device is able to achieve up to 95% efficiency, with very low input output voltage differencing.

The L4973D3.3-013TR also offers a wide range of protection and shutdown features. The device is protected against overtemperature and overcurrent, with auto recovery capabilities. It also includes an adjustable output voltage, which is done using an internal voltage divider, allowing for flexibility in system designs. This can be especially useful in automotive applications where the input voltage can range from 7.5V to 42V.

The L4973D3.3-013TR also offers a multitude of features tailored for the automotive industry. These features include an EMC filter to reduce noise on the vehicle’s power lines, a “dash light-off” feature which shuts off the dash lights when the vehicle is switched off, and a “conditioning” start-up feature which mimics human behaviour by minimizing the inrush current on start-up.

The L4973D3.3-013TR is an ideal choice for applications ranging from automotive, industrial and consumer-level applications. It is able to provide a high level of efficiency, while at the same time providing reliable and adjustable output voltage. The device also provides a great deal of protection against overcurrent, overtemperature and has a number of other features tailored to the automotive industry.
