LTC3728EG#PBF Overview


It comes in the 28-SSOP (0.209, 5.30mm Width) package, which makes switching controller suitable for most applications. For 2 outputs, the dc motor controller is appropriate. Tube solid enclosure protects the pmic. With this function, you can deal with Transistor Driver dc switching's outputs (s). This dc control has a supply voltage and operating voltage of 3.5V~30V. Suitable for work in a -40°C~85°C TA dc switcher. The switching controller can be switched at 260kHz~550kHz. Surface Mount makes it suitable for general dc dc regulator. DCDC regulator is controlled efficiently by Enable, Power Good, Soft Start. Thare switch converters are connected to an analog integrated circuit (IC) of type DUAL SWITCHING CONTROLLER. A switching converters's terminal (s) sits at the DUAL position. 28 terminations with a variety of function. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 15V is input. LTC3728 can be searched for other relevant dc to dc converter ics. There are 28 pins on switching converter. In particular, switching converter is a type of Switching Regulator or Controllers. The test statistics indicate that DC regulator outputs a voltage of 36V. You should note down the dc dc regulator's usual output current of 3A when you start a project. 550kHz is the frequency of the switching controller. Hence, ALSO OPERATES AT 5V is used to better suit the DC to DC voltage regulator's situation. A nominal working status is achieved when the input voltage is set to 15V. The maximum input voltage of this dc switcher is 36V, so users must limit the voltage accordingly. A voltage of 3.5V must be present in the supply. 800mV voltage output is lower than 800mV. In order to ensure high-quality communication, there are 1 channels available. If there is 450μA current flow input, then the switching converter could operate.
