LTC3870IUFD#PBF Overview

This switching controller fits most application requirements since it is packaged in a 28-WFQFN Exposed Pad package. It is sufficient to generate 2 outputs with this dc motor controller. A solid enclosure of Tube surrounds pmic. The program can handle Transistor Driver dc switching's outputs (s). dc control's supply and operating voltages are 4.5V~60V. Worked in an dc switcher with a -40°C~125°C TJ rating. With this switching controller, you can switch at 500kHz. dc dc regulator can be generalized using Surface Mount. Current Limit, Enable, Frequency Control, Phase Control, Soft Start provides dcdc regulator efficient switching control. An analog IC with the DUAL SWITCHING CONTROLLER signal is connected to the switch converters. There are a terminal (s) on the switching converters that are designed at QUAD. A variety of dc switching's functions can be performed on 28 terminations. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 15V is input. A search for "LTC3870" will reveal other relevant dc to dc converter ics. Switching converter type is specifically Switching Regulator or Controllers. dc dc voltage regulators should have a minimum input voltage of 4.5V. The test statistics indicate that DC regulator outputs a voltage of 5.1V. The dc to dc regulator can only accept a maximum input voltage of 60V. In order to satisfy the need, DC to DC voltage regulator has a value of ALSO OPERATES IN ADJUSTABLE MODE FROM 0.5V TO 14V. 0.1A is the largest value switching converter outputs. The dc to dc voltage regulator belongs to the PolyPhase? series.
