LTC3731CG#TRPBF Overview

With a 36-SSOP (0.209, 5.30mm Width) package, the switching controller is suitable for a wide range of applications. 3 outputs are supported by the dc motor controller. Tape & Reel (TR) solid enclosure protects the pmic. A total of Transistor Driver dc switching's outputs can be handled by it. 3.8V~7V is the supply voltage and the operating voltage of the dc control. Suitable for working in an dc switcher that has a 0°C~70°C TA. This switching controller can switch at 225kHz~680kHz. Surface Mount makes it suitable for general dc dc regulator. Featured in the dcdc regulator is Enable, Phase Control, Power Good, Soft Start which allows efficient switching control. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. The switching converters's terminal (s) are designed at DUAL . 36 terminations with a variety of function. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. DC switcher's input voltageis set to 5V. A search for "LTC3731" will reveal other relevant dc to dc converter ics. Total pins of switching converter are 36. Switching converter type is specifically Switching Regulator or Controllers. Input voltage of dc dc voltage regulator must be 4.5V. 750kHz is the maximum frequency of this dc regulators. 5A is the largest value switching converter outputs. The dc to dc voltage regulator is from the PolyPhase? series. There are 1 channels for high-quality communication.
