IRS27951SPBF Product Details

IRS27951SPBF Overview


With a 8-SOIC (0.154, 3.90mm Width) package, the switching controller is suitable for a wide range of applications. For 2 outputs, the dc motor controller is appropriate. A solid enclosure of Tube surrounds pmic. Transistor Driver dc switching's outputs (s) can be handled by it. This dc control has a supply voltage and operating voltage of 12V~18V. Worked in an dc switcher with a -40°C~150°C TJ rating. Switching can be done at Up to 500kHz with this switching controller. The Surface Mount value makes it suitable for general dc dc regulator. For efficient switching control, the dcdc regulator features Enable, Frequency Control. A SWITCHING REGULATOR analog IC is connected to the switch converters. The switching converters's terminals (s) are designed at DUAL. An array of 8 terminations of dc switching. These dc dc converter ics adapt a variety of control techniques, including RESONANT CONTROL. The nominal DC switcher's voltage input is 15V. Search for "IRS27951SPBF" to find other relevant dc to dc converter ics. There are a total of 8 pins on switching converter. In particular, switching converter is a type of Switching Regulator or Controllers. The test statistics indicate that DC regulator outputs a voltage of 18V. You should note that the dc dc regulator's usual output current is 900mA. In most applications and prototypes, DC switcher's Surface Mount makes it suitable. DC regulator has a maximum frequency of 500kHz. Input voltage can be set to 18V for nominal working status. The dc switcher's maximum input voltage is 18V, so users must limit the voltage accordingly. A voltage of 12V is required for the supply. Datasheets indicate that the switching converter can output 18.3V volts at its maximum. There is -300mV voltage output lower than -300mV on the voltage controller. This the controllers dc has a nominal current supply of 300mA.
