LTC3521IUF#PBF Overview


It uses the Tube package in order to optimize the performance of this voltage regulator. As you can see, this harley voltage regulator contains 24 terminations. There is a SWITCHING REGULATOR type analog IC in this voltage regulator 12v that is used to convey analog signals. In order to save space, this harley voltage regulator is available in the 24-WFQFN Exposed Pad package. A total of 3 outputs are configured in this voltage regulator. DC DC switching regulators like this one generate Adjustable outputs on their output pins to handle the power management. As the name implies, this voltage regulator 12v is designed for mounting on a Surface Mount bracket. During switching regulator operation, the operating temperature should remain at -40°C~125°C TJ. There is a switching frequency of 1.1MHz for this voltage regulator 12v. There is no dc to dc voltage regulator's minimum input voltage requirement for this regulator. It is evident from the table below that adjusting voltage regulator's output voltage (Min/Fixed) is equal to 0.6V. DC DC switching regulator's maximum design flexibility comes from its output current of 600mA 1A. 5.5V volts is DC DC switching regulator's maximum input voltage. Its NOT SPECIFIED peak reflow temperature makes this regulator essentially indestructible. To meet the operation requirements, voltage regulator is designed to provide 3.6V as the nominal input voltage. The LTC3521 family of DC/DC regulators includes this DC/DC regulator. There is a possibility that DC DC switching regulator can give voltage at 5.25V volts. During switching regulator operation, 24 pins are used. 1 channels are included in the regulator voltage.
