L4972A Overview
As a result of the use of the Tube package, the performance of this voltage regulator is optimized. In this voltage regulator, there are a total of 20 terminations. The type of analog IC that this voltage regulator is equipped with is SWITCHING REGULATOR. Space-saving 20-DIP (0.300, 7.62mm) packages are available for this harley voltage regulator. In this case, DC DC switching regulator has 1 outputs configured to it. On the output pins of this DC DC switching regulator, there is a Adjustable output generated. This switching regulator is designed to fit the Through Hole mounting system. Keeping dc to dc voltage regulator's operating temperature at -40°C~150°C TJ is essential when operating. 100kHz~200kHz is the switching frequency of this DC-DC switching regulator. This voltage regulator is able to operate with the minimal input voltage of 15V. The voltage regulator 12v is designed to provide a nominal input voltage of 35V for operation. There is a subcategory of this regulator voltage called Switching Regulator or Controllers. In the particular voltage regulators, the L4972 family is represented. There is a possibility that DC DC switching regulator can give voltage at 40V volts. For switching regulator operation, 20 pins are used. In order to use this voltage regulator 12v at its full potential, the output voltage should be kept at at least 5.1V. To meet its operating requirements, dc to dc voltage regulator can deliver a maximum output current of 2A A. With a maximum output voltage of 40V, DC DC switching regulator has a very high efficiency. DC-DC switching regulator with 50V supply voltage. In this case, a dc to dc voltage regulator's minimum supply voltage of 15V volts is required to ensure reliable performance. A frequency of 200kHz permits DC DC switching regulator to maintain a high level of accuracy.
