LTC3548EKD-1 Product Details

LTC3548EKD-1 Overview


As a result of the use of the Tube package, the performance of this voltage regulator is optimized. A voltage regulator consists of 10 terminations. As a matter of fact, the type of analog IC that this voltage regulator 12v is equipped with is called DUAL SWITCHING CONTROLLER. For space-saving purposes, this voltage regulator is available in the 10-UFDFN Exposed Pad package. 2 outputs of voltage regulator are configured. Fixed outputs are generated on the output pins of this adjusting voltage regulator. Switching regulators like this one can be mounted on the Surface Mount mounting system. The operating temperature should be kept at -40°C~85°C TA when the voltage regulator 12v is in operation. DC-DC switching regulators reach 2.25MHz switching frequencies. Voltage regulators like this one can operate at least with 2.5V as the dc to dc voltage regulator's minimum input voltage. The output voltage (Min/Fixed) of this voltage regulator 12v is 1.575V 1.8V. This voltage regulator 12v features maximum design flexibility thanks to its 700mA 1.2A output current. There is a voltage regulator maximum input voltage of 5.5V. As a result of the 260 peak reflow temperature, this 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.
