LTC3731CG#TRPBF Product Details
LTC3731CG#TRPBF Overview
With a 36-SSOP (0.209, 5.30mm Width) package, the switching controller is suitable for a wide range of applications. For 3 outputs, the dc motor controller is appropriate. A solid enclosure of Tape & Reel (TR) surrounds pmic. Transistor Driver dc switching's outputs (s) can be handled by it. This dc control has a supply voltage and operating voltage of 3.8V~7V. Worked in an dc switcher with a 0°C~70°C TA rating. Switching can be done at 225kHz~680kHz with this switching controller. The Surface Mount value makes it suitable for general dc dc regulator. For efficient switching control, the dcdc regulator features Enable, Phase Control, Power Good, Soft Start. A SWITCHING CONTROLLER analog IC is connected to the switch converters. The switching converters's terminals (s) are designed at DUAL. An array of 36 terminations of dc switching. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 5V. Search for "LTC3731" to find other relevant dc to dc converter ics. There are a total of 36 pins on switching converter. In particular, switching converter is a type of Switching Regulator or Controllers. It is recommended that the input voltage of the dc dc voltage regulator be 4.5V. DC regulator has a maximum frequency of 750kHz. Current is output to the greatest value of 5A. The dc to dc voltage regulator belongs to the PolyPhase® series. There are 1 channels for high-quality communication.
