A4490EES-T Product Details

A4490EES-T Overview

This harley voltage regulator utilizes the Tube package for optimized performance. As you can see, this harley voltage regulator contains 20 terminations. There is one type of analog IC that this voltage regulator is equipped with, and that is the SWITCHING REGULATOR type. The space-saving 20-WFQFN Exposed Pad package is available for this voltage regulator. In this case, DC DC switching regulator has 3 outputs configured to it. As you can see, this DC DC switching regulator generates Adjustable output on its output pins. Switching regulators like this one can be mounted on the Surface Mount mounting system. -40°C~85°C TA should be the operating temperature when voltage regulator is operating. The voltage regulator can operate with a dc to dc voltage regulator's minimum input voltage of 4.5V. The output voltage (Min/Fixed) of this voltage regulator 12v is 0.8V. There is a maximum input voltage of 34V for this voltage regulator 12v. With its peak reflow temperature of 260, this voltage regulator is essentially indestructible. The voltage regulator 12v is designed to provide a nominal input voltage of 6V for operation. This DC/DC regulator belongs to the A4490 family. The voltage DC DC switching regulator can provide is up to 5V volts. The switching regulator operation is carried out by 20 pins. This voltage regulator 12v should be configured with an output voltage that is at least 800mV. 30.6V's maximal output voltage allows adjusting voltage regulator to operate easily. As a result, it is able to provide adjusting voltage regulator a maximum output voltage of 30.6V. At a frequency of 550kHz, dc to dc voltage regulator is capable of maintaining high accuracy. Normally, 1.5A is the output current of adjusting voltage regulator.
