LTC3547BEDDB-1#TRPBF Product Details
LTC3547BEDDB-1#TRPBF Overview
A Tape & Reel (TR) package is used in this voltage regulator to optimize performance. During the development of this harley voltage regulator, 8 terminations were made. There is a DUAL SWITCHING CONTROLLER type analog IC in this voltage regulator 12v that is used to convey analog signals. There is a 8-WFDFN Exposed Pad package available for this voltage regulator, as DC DC switching regulator is space-saving. The voltage regulator is configured with 2 outputs. DC DC switching regulators like this one generate Fixed outputs on their output pins to handle the power management. A voltage regulator 12v such as this one fits the Surface Mount mounting bracket. In order for it to operate properly, dc to dc voltage regulator's operating temperature should be at -40°C~85°C TA. The switching frequency of this DC-DC switching regulator reaches 2.25MHz. The voltage regulator can operate with a dc to dc voltage regulator's minimum input voltage of 2.5V. According to the table below, DC DC switching regulator's output voltage (Min/Fixed) is equal to 1.2V 1.8V. A maximum design flexibility is provided by the 300mA output current of voltage regulator. With its peak reflow temperature of 260, this voltage regulator is essentially indestructible. To meet the operation requirements, voltage regulator is designed to provide 3.6V as the nominal input voltage. Listed under the subcategory of Switching Regulator or Controllers is this voltage regulator 12v. In this case, the DC/DC regulator belongs to the family LTC3547. There is a possibility that DC DC switching regulator can give voltage at 5.5V volts. For switching regulator operation, 8 pins are used. With 1 channels, the voltage regulator is equipped.
