    Products Detail

    L4978D Overview


    As a result of the use of the Tube package, the performance of this voltage regulator is optimized. As you can see, this harley voltage regulator contains 16 terminations. There are two types of analog ICs on this voltage regulator. The first type is a SWITCHING REGULATOR-type IC. Space-saving 16-SOIC (0.295, 7.50mm Width) packages are available for this harley voltage regulator. There are 1 outputs configured on the voltage regulator. ICs such as this voltage regulator are capable of generating Adjustable outputs through their output pins. The voltage regulator 12v fits the Surface Mount mounting hole. This voltage regulator 12v should operate at a temperature of -40°C~150°C TJ when operating. 100kHz~300kHz is the switching frequency of this DC-DC switching regulator. A dc to dc voltage regulator's minimum input voltage of 8V is required for this voltage regulator to operate. The maximum input voltage of voltage regulator is 55V. To meet the switching regulator operation requirements, a nominal input voltage of 24V is provided. I would like to point out that this voltage regulator belongs to the Switching Regulator or Controllers subcategory. DC/DC regulators such as this one belong to the L4978 family of products. Voltage of voltage regulator can be delivered at 50V volts. In order to operate voltage regulator, there are 16 pins that must be connected. For this switching regulator, it is recommended that the output voltage is at least 3.3V volts. In order to meet the requirements of the switching regulator operation, the maximum output current reaches 2A A. As a result, it is able to provide adjusting voltage regulator a maximum output voltage of 50V. DC-DC switching regulator with 55V supply voltage. At a frequency of 300kHz, dc to dc voltage regulator is capable of maintaining high accuracy.
