LTC3728LEGN-1#TRPBF Product Details
LTC3728LEGN-1#TRPBF Overview
With a 28-SSOP (0.154, 3.90mm Width) package, the switching controller is suitable for a wide range of applications. 2 outputs can be generated with the dc motor controller. Packaged in solid enclosures, this pmic has a Tape & Reel (TR) rating. It is capable of handling Transistor Driver dc switching's outputs (s). DC control operates at 4.5V~28V volts and has 4.5V~28V supply voltage. Suitable for a -40°C~85°C TA dc switcher. A switching controller such as this can switch at a value of 260kHz~550kHz . dc dc regulators can be carried out with Surface Mount. Enable, Power Good, Soft Start is used for efficient switching control in the dcdc regulator. The switch converters are connected to a DUAL SWITCHING CONTROLLER analog IC. Terminal (s) of the switching converters are designed at the DUAL position. An array of 28 terminations of dc switching. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 15V. You can find other relevant dc to dc converter ics by searching "LTC3728". 28 pins are on switching converter. Switching converter is a special type of Switching Regulator or Controllers. It is recommended that the dc dc voltage regulator's minimum input voltage be 4.5V. The test statistics indicate that DC regulator outputs a voltage of 3.35V. There is a maximum frequency of 590kHz for this dc regulators. Current is output to the greatest value of 3A. In order to ensure high-quality communication, there are 1 channels available.
