LTC3728LIGN-1 Product Details
LTC3728LIGN-1 Overview
It comes in the 28-SSOP (0.154, 3.90mm Width) package, which makes switching controller suitable for most applications. This dc motor controller can be used to generate outputs with 2 numbers. An enclosure of Tube is used to package the PMIC. Transistor Driver dc switching's outputs (s) are supported. 4.5V~35V is the supply voltage and the operating voltage of the dc control. Work well in dc switchers with a -40°C~85°C TA. A switching controller such as this can switch at a value of 260kHz~550kHz . dc dc regulator is made easier with Surface Mount. Enable, Power Good, Soft Start provides dcdc regulator efficient switching control. An analog IC with the DUAL SWITCHING CONTROLLER signal is connected to the switch converters. Terminal (s) of the switching converters are designed at the DUAL position. The 28 terminations can be used for a wide range of dc switching. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. DC switcher's voltage input is 15V. Search for "LTC3728" to find other relevant dc to dc converter ics. There is a particular type of Switching Regulator or Controllers in switching converter. This dc dc voltage regulator should be powered by a voltage of 4.5V. Statistically, the DC regulator outputs 3.35V voltage. Whenever the current value is 3A, switching converter outputs the highest possible value.
