LTC3870EUFD#PBF Overview

The switching controller fits in the 28-WFQFN Exposed Pad package and is ideal for most applications. This dc motor controller can be used to generate outputs with 2 numbers. Packaged in solid enclosures, this pmic has a Tube rating. A total of Transistor Driver dc switching's outputs can be handled by it. The supply and operating voltage of the dc control are 4.5V~60V. A -40°C~125°C TJ dc switcher is not a problem. A switching controller such as this can switch at a value of 500kHz . The Surface Mount value makes it suitable for general dc dc regulator. The dcdc regulator features Current Limit, Enable, Frequency Control, Phase Control for efficient switching control. Switch converters are connected to ICs with DUAL SWITCHING CONTROLLER analog outputs. Thare switching converters has a terminal (s) at QUAD . 28 terminations with a variety of function. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 15V. Search for "LTC3870" to find other relevant dc to dc converter ics. There are 28 pins on switching converter. Specially, switching converter corresponds to type Switching Regulator or Controllers. Based on the test statistics, DC regulator outputs voltage 500mV. DC to DC voltage regulator has the value of ALSO OPERATES IN ADJUSTABLE MODE FROM 0.5V TO 14V to better satisfy the requirement. A maximum value of 0.1A is output for current. It belongs to the PolyPhase? series of dc to dc voltage regulator. The dc switcher's maximum input voltage is 60V; users must limit it accordingly. A voltage of 4.5V must be present in the supply. Its datasheet indicates the switching converter can output a maximum of 14V volts. At its lowest voltage, the voltage controller does not produce less than 500mV.
