LTC3780IUH Overview


This switching controller fits most application requirements since it is packaged in a 32-WFQFN Exposed Pad package. For outputs of 1, this dc motor controller is suitable. An enclosure of Tube is used to package the PMIC. The program can handle Transistor Driver dc switching's outputs (s). This dc control operates at 4V~30V and has a 4V~30V supply voltage. Suitable for a -40°C~125°C TJ dc switcher. Switching can be done at 200kHz~400kHz with this switching controller. dc dc regulators can be carried out with Surface Mount. The dcdc regulator features Current Limit, Enable, Power Good, Soft Start for efficient switching control. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. There are a QUAD terminal on the switching converters. Various 32 terminations. 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. A search for "LTC3780" will reveal other relevant dc to dc converter ics. In particular, switching converter is a type of Switching Regulator or Controllers. It is recommended that the dc dc voltage regulator's minimum input voltage be 4V. It should be noted that the dc to dc regulator only accepts 36V voltage as input voltage. DC to DC voltage regulator has a value of ALSO OUTPUT VOLTAGE ADJUSTABLE 0.8 TO 30V to better satisfy the need. 3A is the largest value switching converter outputs.
