LTC3728LCGN#TRPBF Overview


As a result of 28-SSOP (0.154, 3.90mm Width) compact design, the switching controller is compatible with most applications. There is sufficient capacity to generate switching controller for outputs 2. A solid enclosure of Tape & Reel (TR) surrounds pmic. There are Transistor Driver dc switching's output (s) that it can handle. This dc control operates at 4.5V~28V and has a 4.5V~28V supply voltage. Worked in an dc switcher with a 0°C~85°C TA rating. This switching controller can switch at 260kHz~550kHz. dc dc regulator can be generalized using Surface Mount. In order to control switching efficiently, the dcdc regulator features Enable, Power Good, Soft Start. A DUAL SWITCHING CONTROLLER analog IC is connected to the switch converters. The switching converters's terminals (s) are designed at DUAL. There are many different types of terminations for 28. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. The nominal DC switcher's voltage input is 15V. You can find other relevant dc to dc converter ics by searching "LTC3728". Pins number 28 of switching converter in total. There is a particular type of Switching Regulator or Controllers in switching converter. 3.6V should be the minimum input voltage for the dc dc voltage regulator. DC regulator outputs 7V voltage based on test statistics. The dc to dc regulator can only accept 30V input voltage. DC switcher's Surface Mount qualifies it for most applications and prototypes. DC regulator's maximum frequency is 590kHz. A value of 3A is output as the maximum value of current. It is recommended that there be 1 channels for high-quality communication.
