LT3957AIUHE#PBF Overview
For optimal performance, this voltage regulator makes use of the Tube package. In this voltage regulator, there are 38 terminations. The type of analog IC that this voltage regulator is equipped with is SWITCHING REGULATOR. There is a 36-WFQFN, 28 Leads, Exposed Pad package available for this voltage regulator, as DC DC switching regulator is space-saving. The voltage regulator is configured with 1 outputs. Adjustable outputs are generated on the output pins of this adjusting voltage regulator. There is a switching regulator that is compatible with the Surface Mount mounting. -40°C~125°C TJ should be the operating temperature when voltage regulator is operating. A DC-DC switching regulator of this type operates at a switching frequency of 100kHz~1MHz. This voltage regulator is able to operate with the minimal input voltage of 3V. The output voltage (Min/Fixed) of this voltage regulator 12v is 1.6V. It features maximum design flexibility due to dc to dc voltage regulator's 5A Switch output current. An input voltage of 24V is required for switching regulator operation. DC DC switching regulator is part of the Switching Regulator or Controllers subcategory and can be found in the Switching Regulator or Controllers category. In this case, the DC/DC regulator belongs to the family LT3957. The adjusting voltage regulator's output voltage is maintain at 40V. There are 28 pins used for switching regulator operation. Ideally this switch regulator should have an output voltage of about 1.6V at the very least. By using the 40V Switch's maximal output voltage, adjusting voltage regulator can operate easily. As a result, it is able to provide adjusting voltage regulator a maximum output voltage of 40V.
