LTC3869IGN-2#TRPBF Overview


This switching controller fits most application requirements since it is packaged in a 28-SSOP (0.154, 3.90mm Width) package. 2 outputs are supported by the dc motor controller. Tape & Reel (TR) solid enclosure protects the pmic. The system can process Transistor Driver dc switching's outputs (s). 4V~38V is the supply voltage and the operating voltage of the dc control. Suitable for work in a -40°C~125°C TJ dc switcher. Using this switching controller, it is possible to switch at 250kHz~780kHz. The Surface Mount value makes it suitable for general dc dc regulator. The dcdc regulator features Current Limit, Enable, Frequency Control, Power Good, Soft Start, Tracking for efficient switching control. An analog IC SWITCHING CONTROLLER is connected to the switch converters. switching converters terminal (s) are designed to be at DUAL. Different dc switching's functions can be applied to 28 terminations. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. A DC switcher's nominal voltage of 15V is input. Other relevant dc to dc converter ics will be returned if you search "LTC3869". Total pins of switching converter are 28. dc dc voltage regulators should have a minimum input voltage of 4V. DC regulator outputs 12.5V voltage according to the test statistics. It should be fully noted that the dc to dc regulator only accepts 38V input voltage at most. normally, the dc dc regulator's output current is 25A, which you should keep in mind when starting a project. DC regulator850kHz has the maximum frequency. Channels are 1 for high-quality communication.
