LTC3728LEGN#TRPBF Overview


It comes in the 28-SSOP (0.154, 3.90mm Width) package, which makes switching controller suitable for most applications. 2 outputs can be generated with the dc motor controller. PMIC packaging is solid with a Tape & Reel (TR) enclosure. The system can process Transistor Driver dc switching's outputs (s). DC control operates at 4.5V~28V volts and has 4.5V~28V supply voltage. Work well in dc switchers with a -40°C~85°C TA. Using this switching controller, it is possible to switch at 260kHz~550kHz. dc dc regulator is made easier with Surface Mount. 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. Different dc switching's functions can be applied to 28 terminations. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. It is inputted with a DC switcher's voltage of 15V. A search for "LTC3728" will reveal other relevant dc to dc converter ics. 28 pins are on switching converter. The type is a particular Switching Regulator or Controllers of switching converter. The minimum input voltage of the dc dc voltage regulator should be 3.6V. DC regulator outputs 7V voltage according to the test statistics. This dc to dc regulator accepts only 30V input voltage at most. In most applications and prototypes, DC switcher's Surface Mount makes it suitable. It is estimated that this dc regulatorhas a maximum frequency of 590kHz. A value of 3A is output as the maximum value of current. In order to ensure high-quality communication, there are 1 channels available.
