LTC3731IG#TRPBF Overview


This switching controller fits most application requirements since it is packaged in a 36-SSOP (0.209, 5.30mm Width) package. dc motor controller is suitable for 3 output generation. Packaging for the pmic consists of Tape & Reel (TR) solid enclosures. With this function, you can deal with Transistor Driver dc switching's outputs (s). 3.8V~7V is the operating voltage and supply voltage of the dc control. Suitable for work in a -40°C~85°C TA dc switcher. The switching controller is capable of switching at the 225kHz~680kHz position. It is suitable for general dc dc regulator when it is set to Surface Mount. To provide efficient switching control, Enable, Phase Control, Power Good, Soft Start is included in the dcdc regulator. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. The switching converters's terminal (s) are designed at DUAL . The 36 terminations can be used for a wide range of dc switching. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. DC switcher's input voltageis 5V volts. LTC3731 can be searched for other relevant dc to dc converter ics. The switching converter has a total of 36 pins. There is a particular type of Switching Regulator or Controllers in switching converter. Input voltage of dc dc voltage regulator should be 4.5V. DC regulator has a maximum frequency of 750kHz. The output of this function is the greatest value of 5A. A dc to dc voltage regulator in the PolyPhase? series, it belongs to this family. Communication with high quality requires 1 channels.
