With a wide input voltage range of 3.2V to 28V, it is capable of operating with a wide range of input sources such as AC-DC adapters, 12V battery systems and point-of-load DC-DC converters. This device features an integrated feedback loop and many integrated features making it an attractive choice for modern power supplies. The popularity of this device as an off-line power supply can be attributed to its efficiency and ease of use. When looking at the numbers, the LMR33630ARNXR offers efficiencies of up to 95%, depending on the load and input voltage. Furthermore, it is possible to adjust the output voltage to match the desired domain. Additionally, the device is optimized for continuous switching frequency operation up to 500kHz, allowing for less board space and quicker power supply design times.The LMR33630ARNXR is a switching regulator that works by repeatedly switching a given load on and off. As the load is switched on and off, the device adjusts its output voltage by reacting to the load current. This type of switching regulator is often referred to as a current-mode or voltage-mode controller. By manipulating the current, the output voltage is maintained at a desired level. The switching regulator is able to regulate the load current and assure that the output voltage remains within an acceptable range.The device features a number of features, such as an integrated, low-side gate drive with programmable deadtime control, adjustable frequency, undervoltage and overvoltage lockout and comprehensive soft-start. The programmable deadtime control allows the user to adjust the minimum switch-on and switch-off times, resulting in improved efficiency and reduced heat dissipation. Furthermore, the adjustable frequency allows for a wider range of power solutions, and the undervoltage and overvoltage lockout protect the device from excessive voltages that may be present in the power supply. Finally, the soft-start feature provides a gradual start to the power supply, protecting any sensitive electronic components.The LMR33630ARNXR is a great choice for a wide range of applications, from personal computing and industrial uses to small appliance and lightweight automotive applications. Furthermore, with its energy efficiency and module size, it is both economical and space-saving. In summary, the LMR33630ARNXR is a powerful integrated device and PMIC - Voltage Regulators - DC DC Switching Regulators ideal for off-line, isolated power supplies. It offers a wide range of features such as an integrated feedback loop, undervoltage and overvoltage lockout, adjustable frequency and comprehensive soft-start. It is perfect for a wide variety of applications and provides excellent efficiency and space-saving benefits.
