LTC3546IUFD#PBF Overview
optimized performance is achieved by utilizing the Tube package in this voltage regulator. In this voltage regulator, there are a total of 28 terminations. A DUAL SWITCHING CONTROLLER type of analog IC is equipped with this regulator voltage, which is the type of analog IC that is used in it. In order to save space, this voltage regulator is packaged in the 28-WFQFN Exposed Pad package. The voltage regulator 12v has 2 outputs. As you can see, this DC DC switching regulator generates Adjustable output on its output pins. A voltage regulator 12v such as this one fits the Surface Mount mounting bracket. -40°C~125°C TJ should be the operating temperature when voltage regulator is operating. The switching frequency of this DC-DC switching regulator reaches 2.25MHz 750kHz~4MHz. The regulator is capable of operating with a dc to dc voltage regulator's minimum input voltage of 2.3V. In this adjusting voltage regulator, the output voltage (Min/Fixed) equates to 0.6V. A maximum design flexibility is provided by the 1A 2A output current of voltage regulator. Voltage regulators' input voltage is limited to 5.5V. Due to its 250 high peak reflow temperature, this voltage regulator 12v is virtually indestructible. An input voltage of 3.6V 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. As a member of the LTC3546 family of DC/DC regulators, this is a DC/DC regulator. At 5V volts, voltage regulator can provide voltage. In order to operate voltage regulator, there are 28 pins that must be connected. This voltage regulator 12v should be configured with an output voltage that is at least 600mV. Switching regulator has a maximum output current of 2A A, which is sufficient to meet the requirements of operation. With a maximum output voltage of 5V, DC DC switching regulator has a very high efficiency. It has 1 channels of voltage regulator.
