    Products Detail

    PM6644TR Overview


    There is an optimized performance in this voltage regulator because it utilizes the Tape & Reel (TR) package. This harley voltage regulator has 10 terminations. This regulator voltage is equipped with a type of analog integrated circuit that is called a SWITCHING REGULATOR voltage regulator. Due to DC DC switching regulator's space saving design, this voltage regulator is available in a 10-VFDFN Exposed Pad package. In this case, DC DC switching regulator has 1 outputs configured to it. DC DC switching regulators like this one generate Adjustable (Fixed) outputs on their output pins to handle the power management. This switching regulator is designed to fit the Surface Mount mounting system. Operating at -40°C~125°C TJ is the recommended temperature for adjusting voltage regulator's operation. A DC-DC switching regulator of this type operates at a switching frequency of 200kHz~600kHz. There is no dc to dc voltage regulator's minimum input voltage requirement for this regulator. The adjusting voltage regulator's output voltage (Min/Fixed) is 0.9V 3.47V. 25V volts is DC DC switching regulator's maximum input voltage. An input voltage of 12V is required for switching regulator operation. DC DC switching regulator is part of the Switching Regulator or Controllers subcategory and can be found in the Switching Regulator or Controllers category. DC/DC regulators of this type are part of the PM6644 family of voltage regulator 12vs. A voltage of 8V volts can be produced by voltage regulator. For switching regulator operation, 10 pins are used. As a general rule, this voltage regulator 12v should keep its output voltage at least at 900mV. To meet its operating requirements, dc to dc voltage regulator can deliver a maximum output current of 350mA A. An output voltage of 8V is provided by this regulator voltage. A harley voltage regulator operates with a 4.2V supply voltage.
