LTC3547EDDB-1#TRMPBF Product Details
LTC3547EDDB-1#TRMPBF Overview
It is designed to provide optimal performance by utilizing the Tape & Reel (TR) package. In this voltage regulator, there are 8 terminations. There is one type of analog IC that this voltage regulator is equipped with, and that is the DUAL SWITCHING CONTROLLER type. For space-saving purposes, this voltage regulator is available in the 8-WFDFN Exposed Pad package. There are 2 outputs configured on the voltage regulator. DC DC switching regulators like this one generate Fixed outputs on their output pins to handle the power management. Surface Mount-mounting is compatible with this switching regulator. In order for it to operate properly, dc to dc voltage regulator's operating temperature should be at -40°C~85°C TA. Voltage regulator's switching frequency reaches 2.25MHz. Voltage regulators like this one can operate at least with 2.5V as the dc to dc voltage regulator's minimum input voltage. The adjusting voltage regulator's output voltage (Min/Fixed) is 1.2V 1.8V. DC DC switching regulator's 300mA output current allows for maximum design flexibility. A regulator with this 260 peak reflow temperature is essentially indestructible. Voltage regulator is designed to provide a nominal input voltage of 3.6V to meet the operation requirements. As part of the LTC3547 series of regulators, the voltage regulators can be found. Voltage of voltage regulator can be delivered at 5.5V volts. To operate the voltage regulator 12v, 8 pins are required. There should be at least a 1.8V volt output voltage for this switching regulator in order to make it work properly. I would like to point out that the voltage regulator 12v has 1 channels.
