LTC3728LEGN#TRPBF Product Details
LTC3728LEGN#TRPBF Overview
Capsuled in the 28-SSOP (0.154, 3.90mm Width) package, the switching controller suits most application needs. The dc motor controller is adquate to generate for 2 outputs. The pmic is packaged in Tape & Reel (TR) solid enclosure. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sThe supply and operating voltage of the dc control are 4.5V~28V. Qualified to work in a -40°C~85°C TA dc switcher. This switching controller can switch at 260kHz~550kHz. Surface Mount makes it suitable for general dc dc regulator. The dcdc regulator features Enable, Power Good, Soft Start for efficient switching control. The switch converters are connected to a DUAL SWITCHING CONTROLLER analog IC. Terminal (s) of the switching converters are designed at the DUAL position. 28 terminations with a variety of function. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. 15V nominal DC switcher's voltage input. Other relevant dc to dc converter ics can be found by searching "LTC3728". Switching converter has a total of 28 pins. Switching converter is a type of Switching Regulator or Controllers in particular. The minimum input voltage of the dc dc voltage regulator should be 3.6V. According to the test statistics, DC regulator outputs 7V voltage. It should be fully noted that the dc to dc regulator only accepts 30V input voltage at most. DC switcher's Surface Mount makes it qualified for most application and prototype designs. DC switcher'sThe max frequency of the pmic can reach 590kHz. Switching converter outputs current to the greatest value of 3A. For high-quality communication, there are 1 channels.
