LTC3728LIGN-1#TRPBF Overview


The switching controller fits in the 28-SSOP (0.154, 3.90mm Width) package and is ideal for most applications. The dc motor controller is adquate to generate for 2 outputs. Packaging for the pmic consists of Tape & Reel (TR) solid enclosures. With Transistor Driver dc switching's output (s), it is able to handle it. The supply and operating voltage of the dc control are 4.5V~35V. Worked in an dc switcher with a -40°C~85°C TA rating. A switching controller such as this can switch at a value of 260kHz~550kHz . The Surface Mount value makes it suitable for general dc dc regulator. In order to control switching efficiently, the dcdc regulator features Enable, Power Good, Soft Start. Connected to a DUAL SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. The switching converters's terminals (s) are designed at DUAL. Different dc switching's functions can be applied to 28 terminations. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 15V. Other relevant dc to dc converter ics will be returned if you search "LTC3728". There are 28 pins on switching converter. The type is a particular Switching Regulator or Controllers of switching converter. An input voltage of 4.5V is the minimum required for the dc dc voltage regulator. A 3.35V voltage of DC regulator was detected in the test statistics. In most cases, the dc dc regulator's output current is 3A. This information should be noted when you begin working with the component. As DC switcher has a Surface Mount, it's suitable for most applications and prototype designs. DC regulator's maximum frequency is 590kHz. There are 1 channels for high-quality communication.
