IR3891MTR1PBF Product Details

IR3891MTR1PBF Overview


For optimal performance, this voltage regulator uses the Tape & Reel (TR) package. Space-saving 31-PowerVFQFN packages are available for this harley voltage regulator. The voltage regulator 12v has 2 outputs. Adjusting voltage regulator's output pins generate Adjustable output. A voltage regulator 12v such as this one fits the Surface Mount mounting bracket. As long as its operating temperature is -40°C~125°C TJ, dc to dc voltage regulator should perform well. In this voltage regulator 12v, the switching frequency is 300kHz~1.5MHz. The voltage regulator can be operated with a voltage as low as 1V as an input voltage. As a result, the output voltage of the voltage regulator 12v (Min/Fixed) is 0.5V. DC DC switching regulator's maximum design flexibility comes from its output current of 4A. Voltage regulator's input voltage can reach 21V. DC/DC regulators such as this one belong to the IR3891 family of products. At 18.06V volts, voltage regulator can provide voltage. To operate the voltage regulator 12v, 31 pins are required. In order for this switching regulator to work properly, the output voltage should be at least 500mVV. Accordingly, dc to dc voltage regulator's maximum output current is 4A A. On the basis of 18.06V's maximal output voltage, DC DC switching regulator can be operated easily. As a result, it is able to provide adjusting voltage regulator a maximum output voltage of 18.06V. In the SupIRBuck? family, this part palys an important role in DC DC switching regulator's traget applications. With a supply voltage of 21V, this harley voltage regulator works. Adjusting voltage regulator reliable performance is ensured based on the minimal supply voltage of 1V V. A high maximum operating temperature 125°C ensures stable operation of switching regulator. Reliability is ensured at minimum DC DC switching regulator's operating temperatures of -40°C. The voltage regulator 12v supports a dc to dc voltage regulator's minimum input voltage of 1V for its input. This DC-DC switching regulator is designed to sustain a 21V input voltage at its maxium.
