LTC3851AHMSE-1#TRPBF Overview
In the 16-TFSOP (0.118, 3.00mm Width) Exposed Pad package, the switching controller meets most application requirements. 1 outputs can be generated with the dc motor controller. An enclosure of Tape & Reel (TR) is used to package the PMIC. With Transistor Driver dc switching's output (s), it is able to handle it. A 4V~38V voltage is supplied to the dc control and used for operating it. Workable in an dc switcher where -40°C~150°C TJ is the -40°C~150°C TJrm. Switching can be done at 235kHz~750kHz with this switching controller. dc dc regulators can be carried out with Surface Mount. Enable, Frequency Control, Power Good, Soft Start, Tracking provides dcdc regulator efficient switching control. A SWITCHING CONTROLLER analog IC is connected to the switch converters. There are a DUAL terminal on the switching converters. Various 16 terminations. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. DC switcher's voltage input is 15V. LTC3851 can be searched for other relevant dc to dc converter ics. Total pins of switching converter are 16. Specifically, switching converter falls under the Switching Regulator or Controllers category. This dc dc voltage regulator should be powered by a voltage of 4V. Statistically, DC regulator outputs 5.5V volts. The dc to dc regulator can only accept a maximum input voltage of 38V. 810kHz is the maximum frequency of this dc regulators. As a result, DC to DC voltage regulator has a value of ALSO OPERATES IN ADJUSTABLE MODE FROM 0.8V TO 5.5V so that the need can be met more directly. 0.05A is the greatest value switching converter outputs as current.
