LTC3855EFE Overview
This switching controller fits most application requirements since it is packaged in a 38-TFSOP (0.173, 4.40mm Width) Exposed Pad package. For outputs of 2, this dc motor controller is suitable. There is a Tube solid enclosure around the pmic. It is capable of handling Transistor Driver dc switching's outputs (s). Voltages 4.5V~38V are the dc control's supply voltage and operating voltage, respectively. Qualified to work in a -40°C~85°C TA dc switcher. A switching controller such as this can switch at a value of 250kHz~770kHz . dc dc regulator is made easier with Surface Mount. Featured in the dcdc regulator is Current Limit, Enable, Frequency Control, Phase Control, Power Good, Soft Start, Tracking which allows efficient switching control. A DUAL SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. DUAL are the position of the terminal of the switching converters. Various 38 terminations. Some of the control techniques used by these dc dc converter ics are PHASE-SHIFT CONTROL. DC switcher's voltage input of 15V. Other relevant dc to dc converter ics will be returned if you search "LTC3855". Specially, switching converter corresponds to type Switching Regulator or Controllers. 4.5V should be the minimum input voltage for the dc dc voltage regulator. This dc to dc regulator accepts only 38V input voltage at most. PolyPhase? is a series of dc to dc voltage regulator.
