LM3668SDX-4550/NOPB Product Details

LM3668SDX-4550/NOPB Overview


There is an optimized performance in this voltage regulator because it utilizes the Tape & Reel (TR) package. There are 12 terminations in this harley voltage regulator. This regulator voltage is equipped with a type of analog integrated circuit that is called a DUAL SWITCHING CONTROLLER voltage regulator. Space-saving 12-WFDFN Exposed Pad packages are available for this harley voltage regulator. There are 1 outputs configured on the voltage regulator. DC DC switching regulators like this one generate Programmable outputs on their output pins to handle the power management. There is a switching regulator that is compatible with the Surface Mount mounting. When operating, adjusting voltage regulator's operating temperature should be kept at -40°C~85°C TA. This DC-DC switching regulator has a switching frequency of 2.2MHz. There is no dc to dc voltage regulator's minimum input voltage requirement for this regulator. As a result, the output voltage of the voltage regulator 12v (Min/Fixed) is 4.5V 5V. Voltage regulator's input voltage can reach 5.5V. Its 260 peak reflow temperature makes this regulator essentially indestructible. In terms of category, this voltage regulator 12v falls into the Switching Regulator or Controllers category. DC/DC regulators of this type are part of the LM3668 family of voltage regulator 12vs. Voltage of voltage regulator can be delivered at 5V volts. There are 12 pins that are used for the operation of the voltage regulator 12v. The maximum output current reaches 1A A to meet the switching regulator operation requirements. An input voltage of 5.5V is used to operate this harley voltage regulator. There are no external factors that affect DC DC switching regulator's consumption of 45μA A of quiescent current.
