BD9775FV-E2 Overview


With its 28-LSSOP (0.220, 5.60mm Width) package, the switching controller fits the needs of most applications. There is enough capacity in the dc motor controller to generate the output for the 2 input. Tape & Reel (TR) solid enclosure protects the pmic. Transistor Driver dc switching's outputs (s) are supported. This dc control has a supply voltage and operating voltage of 6V~30V. Qualified to work in a -40°C~85°C TA dc switcher. It can switch at 30kHz~300kHz. dc dc regulator can be generalized using Surface Mount. For efficient switching control, the dcdc regulator features Enable, Frequency Control, Soft Start. An analog IC with the DUAL SWITCHING CONTROLLER signal is connected to the switch converters. Switching converters are designed with the terminal (s) at position DUAL . Various 28 terminations. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's voltage input of 13.2V. You can find other relevant dc to dc converter ics by searching "BD9775". Pins number 28 of switching converter in total. Specially, switching converter corresponds to type Switching Regulator or Controllers. 6V should be the minimum input voltage for the dc dc voltage regulator. Statistically, the DC regulator outputs 2.4V voltage. Voltage regulator dc to dc is designed to operate at 45 % duty cycle during power-ups and power-downs to ensure reliability. Having a Surface Mount makes DC switcher ideal for most prototype and application designs. In order to run the voltage regulator dc to dc safely and reliably, users are advised to apply 30V. It runs on a supply current of 4.2mA.
