MAX1843ETI+ Overview
As a result of the use of the Tube package, the performance of this voltage regulator is optimized. There are 28 terminations in this harley voltage regulator. A SWITCHING REGULATOR analog IC is used in this voltage regulator 12v, which is the type of analog IC that this voltage regulator 12v is equipped with. Due to DC DC switching regulator's space saving design, this voltage regulator is available in a 28-WFQFN Exposed Pad package. 1 outputs have been configured in the voltage regulator 12v. This DC DC switching regulator generates Adjustable (Programmable) output on its output pins. 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. 1MHz is the switching frequency of this DC-DC switching regulator. Voltage regulators like this one can operate at least with 3V as the dc to dc voltage regulator's minimum input voltage. In this adjusting voltage regulator, the output voltage (Min/Fixed) equates to 1.1V 1.5V 1.8V 2.5V. As far as the voltage input is concerned, DC DC switching regulator can accept up to 5.5V. Its 260 peak reflow temperature makes this regulator essentially indestructible. In order to meet the operation requirements,voltage regulator is designed to provide a nominal input voltage of 3.3V. There is a subcategory of this regulator voltage called Switching Regulator or Controllers. This DC/DC regulator belongs to the MAX1843 family. The adjusting voltage regulator's output voltage is maintain at 2.5V. In order to operate voltage regulator, 28 pins are required. In order to meet the requirements of the switching regulator operation, the maximum output current reaches 2.7A A. This DC-DC switching regulator operates from a supply voltage of 5.5V.
