LT3991EDD Product Details

LT3991EDD Overview


As a result of the use of the Tube package, the performance of this voltage regulator is optimized. As you can see, this harley voltage regulator contains 10 terminations. There are two types of analog ICs on this voltage regulator. The first type is a SWITCHING REGULATOR-type IC. Space-saving 10-WFDFN Exposed Pad packages are available for this harley voltage regulator. There are 1 outputs configured on the voltage regulator. ICs such as this voltage regulator are capable of generating Adjustable outputs through their output pins. The voltage regulator 12v fits the Surface Mount mounting hole. This voltage regulator 12v should operate at a temperature of -40°C~125°C TJ when operating. 200kHz~2MHz is the switching frequency of this DC-DC switching regulator. A dc to dc voltage regulator's minimum input voltage of 4.3V is required for this voltage regulator to operate. The output voltage of this voltage regulator (Min/Fixed) amounts to 1.19V volts. Featuring a maximum design flexibility of 1.2A, dc to dc voltage regulator has a maximum output current of 1.2A. The maximum input voltage of voltage regulator is 55V. As a result of its peak reflow temperature, this voltage regulator is virtually indestructible. To meet the switching regulator operation requirements, a nominal input voltage of 12V is provided. I would like to point out that this voltage regulator belongs to the Switching Regulator or Controllers subcategory. Voltage of voltage regulator can be delivered at 3.3V volts. 30V's maximal output voltage allows adjusting voltage regulator to operate easily.
