MAX1843ETI+T Product Details
MAX1843ETI+T Overview
As a result of the use of the Tape & Reel (TR) package, the performance of this voltage regulator is optimized. In this voltage regulator, 28 terminations are present. There is one type of analog IC that this voltage regulator is equipped with, and that is the SWITCHING REGULATOR type. This harley voltage regulator is available in the 28-WFQFN Exposed Pad package for the purpose of space saving. 1 outputs have been configured in the voltage regulator 12v. On the output pins of this DC DC switching regulator, there is a Adjustable (Programmable) output generated. Surface Mount-mounting is compatible with this switching regulator. 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 1MHz. Voltage regulators like this one can operate at least with 3V as the dc to dc voltage regulator's minimum input voltage. The output voltage (Min/Fixed) of this voltage regulator 12v is 1.1V 1.5V 1.8V 2.5V. The maximum input voltage of voltage regulator is 5.5V. This voltage regulator's peak reflow temperature is so high as to make it virtually indestructible. The voltage regulator 12v is designed to provide a nominal input voltage of 3.3V for operation. In terms of category, this voltage regulator 12v falls into the Switching Regulator or Controllers category. DC/DC regulators such as this one belong to the MAX1843 family of products. A voltage of 2.5V volts can be generated by DC DC switching regulator. There are 28 pins that are used for the operation of the voltage regulator 12v. In order to meet the requirements of the switching regulator operation, the maximum output current reaches 2.7A A. DC-DC switching regulator with supply voltage 5.5V.
