MAX1945SEUI+T Product Details
MAX1945SEUI+T Overview
As a result of the use of the Tape & Reel (TR) package, the performance of this voltage regulator is optimized. As you can see, this harley voltage regulator contains 28 terminations. As a matter of fact, the type of analog IC that this voltage regulator 12v is equipped with is called SWITCHING REGULATOR. In order to save space, this voltage regulator is packaged in the 28-TSSOP (0.173, 4.40mm Width) Exposed Pad package. DC DC switching regulator is configured with 1 outputs. As you can see, this DC DC switching regulator generates Adjustable (Programmable) output on its output pins. A Surface Mount mounting is required for this switching regulator. In order for it to operate properly, dc to dc voltage regulator's operating temperature should be at -40°C~85°C TA. A DC-DC switching regulator of this type operates at a switching frequency of 400kHz~1.2MHz. The voltage regulator can be operated with a voltage as low as 2.6V as an input voltage. There is a adjusting voltage regulator's voltage output (Min/Fixed) of 0.8V 1.8V 2.5V. Featuring a maximum design flexibility of 6A, dc to dc voltage regulator has a maximum output current of 6A. A regulator voltage's peak reflow temperature amounts to 260 being indestructible. An input voltage of 3.3V is required to meet the requirements of the switching regulator operation. This DC/DC regulator belongs to the MAX1945 family. The voltage DC DC switching regulator can produce is 2.5V volts. For switching regulator operation, 28 pins are used. On the basis of the maximum output voltage of 4.68V, adjusting voltage regulator can be operated easily. A harley voltage regulator operates with a 5.5V supply voltage.
