LTC3728LZEUH#TRPBF Product Details

LTC3728LZEUH#TRPBF Overview


The switching controller fits in the 32-WFQFN Exposed Pad package and is ideal for most applications. dc motor controller is suitable for 2 output generation. Packaged in solid enclosures, this pmic has a Tape & Reel (TR) rating. There are Transistor Driver dc switching's output (s) that it can handle. A 4.5V~28V voltage is supplied to the dc control and used for operating it. Suitable for work in a -40°C~85°C TA dc switcher. With this switching controller, you can switch at 260kHz~550kHz. The Surface Mount makes it ideal for general dc dc regulator. Featured in the dcdc regulator is Enable, Power Good, Soft Start which allows efficient switching control. Thare switch converters are connected to an analog integrated circuit (IC) of type DUAL SWITCHING CONTROLLER. There are a terminal (s) on the switching converters that are designed at QUAD. 28 terminations with various dc switching's functions. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. The DC switcher's nominal voltage is 15V. Other relevant dc to dc converter ics will be returned if you search "LTC3728". Total pins of switching converter are 32. It is recommended to use 4.5V as the minimum input voltage of dc dc voltage regulator. There is a maximum frequency of 590kHz for this dc regulators. Whenever the current value is 3A, switching converter outputs the highest possible value. It is recommended that there be 1 channels for high-quality communication.
