LT1249CS8#PBF Overview
Currently, it is available as a 8-SOIC (0.154, 3.90mm Width) package.A Tube-package is used.There is a Surface Mount mounting type for the device.The voltage supply of 15.5V~27V should be used.At 0°C~100°C, the device operates.Other IC types, such as POWER FACTOR CONTROLLER, are present in the part.There are a number of 8 terminals on the gadget.Current startup is 250μA.This component retains the pin number at 8 even though the pin number has been changed.One of the device's best parts is that it has a number of LT1249 on it.100kHz is the switching frequency.There are a total of 8 pins on it.Switching Regulator or Controllers is a subclass of it in some ways.When the frequency is 125kHz, it is still able to maintain good accuracy.There should be a limit on ISUP, the maximum supply current, so that it does not exceed 12mA.There are many types of 3 outputs that can be generated.It is set to 9mA for the gadget's supply current.As long as the 5V output is used, it can be controlled.
