BD9673AEFJ-E2 Product Details

BD9673AEFJ-E2 Overview

optimized performance is achieved by utilizing the Tape & Reel (TR) package in this voltage regulator. The space-saving 8-SOIC (0.154, 3.90mm Width) Exposed Pad 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 Surface Mount bracket. During switching regulator operation, the operating temperature should remain at -40°C~105°C TA. This voltage regulator 12v reaches a switching frequency of 300kHz. The regulator is capable of operating with a dc to dc voltage regulator's minimum input voltage of 7V. As shown in the table below, adjusting voltage regulator's output voltage (Min/Fixed) is equal to 1V. A maximum design flexibility is provided by the 1.5A output current of voltage regulator. There is a maximum input voltage of 42V for this voltage regulator 12v. A voltage of 29.4V volts can be generated by DC DC switching regulator. There are 8 pins used for switching regulator operation. For this switching regulator, we recommend keeping the output voltage at at least 1V volts. A 1.5A A maximum output current is required to meet the switching regulator operation requirements. By using the 29.4V's maximal output voltage, adjusting voltage regulator can operate easily. With a maximum output voltage of 29.4V, DC DC switching regulator has a very high efficiency. With 42V as the supply voltage, this DC-DC switching regulator will operate. This voltage regulator allows stable operation due to its high maximum operating temperature 105°C. Reliability is ensured at minimum DC DC switching regulator's operating temperatures of -40°C. With regard to the input voltage, it is compatible with a minimum voltage of 7V. 42V input voltage is supported at its maximum by this voltage regulator 12v.
