L4972AD Overview
A Tube package is used in this voltage regulator to optimize performance. Throughout this voltage regulator, there are 20 terminations. As this regulator voltage is equipped with an analog IC of the type SWITCHING REGULATOR, it is a SWITCHING REGULATOR-type voltage regulator. For space-saving purposes, this voltage regulator is available in the 20-SOIC (0.295, 7.50mm Width) package. There are 1 outputs configured on this voltage regulator 12v. As you can see, this DC DC switching regulator generates Adjustable output on its output pins. This switching regulator is designed to fit the Surface Mount mounting system. Keeping dc to dc voltage regulator's operating temperature at -40°C~150°C TJ is essential when operating. This DC-DC switching regulator has a switching frequency of 100kHz~200kHz. A dc to dc voltage regulator's minimum input voltage of 15V is required for this voltage regulator to operate. The maximum input voltage of voltage regulator is 50V. A regulator with this 260 peak reflow temperature is essentially indestructible. To meet the switching regulator operation requirements, a nominal input voltage of 35V is provided. This voltage regulator is included in the Switching Regulator or Controllers subcategory. This DC/DC regulator belongs to the L4972 family. The voltage DC DC switching regulator can produce is 40V volts. 20 pins are used for switching regulator operation. The output voltage of this voltage regulator 12v should at least be set at 5.1V volts at all times. A maximum output current of 2A A is provided to meet the switching regulator operation requirements. It provides the adjusting voltage regulator's maximal output voltage of 40V. With 50V as the supply voltage, this DC-DC switching regulator will operate.
