LTC3855IFE Overview
Capsuled in the 38-TFSOP (0.173, 4.40mm Width) Exposed Pad package, the switching controller suits most application needs. For outputs of 2, this dc motor controller is suitable. Tube solid enclosure protects the pmic. Transistor Driver dc switching's outputs (s) are supported. This dc control operates at 4.5V~38V and has a 4.5V~38V supply voltage. A -40°C~125°C TJ dc switcher is not a problem. With this switching controller, you can switch at 250kHz~770kHz. The Surface Mount makes it ideal for general dc dc regulator. To provide efficient switching control, Current Limit, Enable, Frequency Control, Phase Control, Power Good, Soft Start, Tracking is included in the dcdc regulator. A DUAL SWITCHING CONTROLLER analog IC is connected to the switch converters. The switching converters's terminal (s) are designed at DUAL . The 38 terminations can be used for a wide range of dc switching. The control methods that these dc dc converter ics use include PHASE-SHIFT CONTROL. DC switcher's voltage input is 15V. Other relevant dc to dc converter ics can be found by searching "LTC3855". Switching converter type is specifically Switching Regulator or Controllers. It is recommended that the input voltage of the dc dc voltage regulator be 4.5V. The dc to dc regulator is limited to 38V input voltage. There are several dc to dc voltage regulator in the PolyPhase? series.
