NCP1581DR2G Overview


With a 14-SOIC (0.154, 3.90mm Width) package, the switching controller is suitable for a wide range of applications. 1 outputs can be generated with the dc motor controller. Packaging for the pmic consists of Tape & Reel (TR) solid enclosures. There are Transistor Driver dc switching's output (s) that it can handle. 6.3V~20V is the supply voltage and the operating voltage of the dc control. Work well in dc switchers with a 0°C~125°C TJ. Using this switching controller, it is possible to switch at 400kHz. dc dc regulator is made easier with Surface Mount. Enable, Soft Start provides dcdc regulator efficient switching control. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. Thare switching converters has a terminal (s) at DUAL . 14 terminations with a variety of function. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's input voltageis 12V volts. Other relevant dc to dc converter ics can be found by searching "NCP1581". Switching converter has a total of 14 pins. Input voltage of dc dc voltage regulator must be 7V. It should be fully noted that the dc to dc regulator only accepts 20V input voltage at most. If you start a project, note down the dc dc regulator's usual output current of 100μA. It is set to 95 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. This Surface Mount makes DC switcher suitable for most prototypes and applications. DC regulators have a maximum frequency of 430kHz. 15mA volts is the supply current. This the controllers dc has a nominal current supply of 15mA.
