    Products Detail

    L4974A Overview


    optimized performance is achieved by utilizing the Tube package in this voltage regulator. Throughout this voltage regulator, there are 20 terminations. There are two types of analog ICs in this voltage regulator 12v: SWITCHING REGULATOR ICs, which are the ones used in older voltage regulator 12vs. The space-saving 20-DIP (0.300, 7.62mm) package is available for this voltage regulator. The voltage regulator 12v has 1 outputs. The adjusting voltage regulator generates Adjustable output. As the name implies, this voltage regulator 12v is designed for mounting on a Through Hole bracket. During switching regulator operation, the operating temperature should remain at -40°C~150°C TJ. This voltage regulator 12v reaches a switching frequency of 100kHz~200kHz. The regulator is capable of operating with a dc to dc voltage regulator's minimum input voltage of 15V. The voltage regulator 12v is designed to provide a nominal input voltage of 35V for operation. In terms of category, this voltage regulator 12v falls into the Switching Regulator or Controllers category. In the particular voltage regulators, the L4974 family is represented. A voltage of 40V volts can be generated by DC DC switching regulator. There are 20 pins used for switching regulator operation. For this switching regulator, we recommend keeping the output voltage at at least 5.1V volts. A 3.5A A maximum output current is required to meet the switching regulator operation requirements. By using the 40V's maximal output voltage, adjusting voltage regulator can operate easily. With a maximum output voltage of 40V, DC DC switching regulator has a very high efficiency. With 50V as the supply voltage, this DC-DC switching regulator will operate. A frequency of 200kHz enables dc to dc voltage regulator to maintain high accuracy.
