LTC3851AHMSE#PBF Product Details

LTC3851AHMSE#PBF Overview


Capsuled in the 16-TFSOP (0.118, 3.00mm Width) Exposed Pad package, the switching controller suits most application needs. 1 outputs are supported by the dc motor controller. Packaged in solid enclosures, this pmic has a Tube rating. With Transistor Driver dc switching's output (s), it is able to handle it. dc controls with 4V~38V voltage are supplied and operated. Qualified to work in an dc switcher with -40°C~150°C TJ. The switching controller can be switched at 235kHz~750kHz. The Surface Mount allows it to be used for dc dc regulator in general. DCDC regulator is controlled efficiently by Current Limit, Enable, Frequency Control, Soft Start, Tracking. SWITCHING REGULATOR analog IC connects the switch converters. DUAL are the position of the terminal of the switching converters. A variety of dc switching's functions can be performed on 16 terminations. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. DC switcher's input voltageis set to 15V. Other relevant dc to dc converter ics can be found by searching "LTC3851". 16 pins are on switching converter. Specifically, switching converter falls under the Switching Regulator or Controllers category. 4V should be the minimum input voltage for the dc dc voltage regulator. Statistically, the DC regulator outputs 5.5V voltage. It should be noted that the dc to dc regulator only accepts 38V voltage as input voltage. You should note down the dc dc regulator's usual output current of 25A when you start a project. It is estimated that this dc regulatorhas a maximum frequency of 810kHz. The value of DC to DC voltage regulator is set to ALSO OPERATES AS LDO REGULATOR, OPERATES IN ADJUSTABLE MODE FROM 0.8 TO 5.5V in order to better satisfy the requirement.
