BD9778F-E2 Product Details

BD9778F-E2 Overview


It is designed to provide optimal performance by utilizing the Tape & Reel (TR) package. There are 8 terminations in this harley voltage regulator. 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 8-SOIC (0.173, 4.40mm Width) package. A total of 1 outputs are configured in this voltage regulator. On the output pins of this DC DC switching regulator, there is a Adjustable output generated. Surface Mount-mount switching regulator. -40°C~125°C TA should be the operating temperature when voltage regulator is operating. Voltage regulator's switching frequency reaches 50kHz~500kHz. The voltage regulator can be operated with a voltage as low as 7V as an input voltage. According to the table below, DC DC switching regulator's output voltage (Min/Fixed) is equal to 1V. DC DC switching regulator's 2A output current allows for maximum design flexibility. To meet the operation requirements, voltage regulator is designed to provide 13.2V as the nominal input voltage. The regulator voltage is included in the Switching Regulator or Controllers subcategory of voltage regulators. In this case, the DC/DC regulator belongs to the family BD9778. Voltage can be produced at 35V volts by voltage regulator. The switching regulator operation of the system is controlled by 8 pins. In order to use this voltage regulator 12v at its full potential, the output voltage should be kept at at least 1V. The maximum voltage of voltage regulator 12v DC DC switching regulator can produce is 35V, which is the highest available. An input voltage of 35V is used to operate this harley voltage regulator.
