LTC3859ALHUHF#TRPBF Product Details
LTC3859ALHUHF#TRPBF Overview
With its 38-WFQFN Exposed Pad package, the switching controller fits the needs of most applications. 3 outputs are supported by the dc motor controller. Tape & Reel (TR) solid enclosure protects the pmic. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sDC control operates at 4.5V~38V volts and has 4.5V~38V supply voltage. Suitable for work in a -40°C~150°C TJ dc switcher. In this switching controller, the switch can be set to 115kHz~835kHz 350kHz~535kHz. Surface Mount makes it suitable for general dc dc regulator. For efficient switching control, the dcdc regulator features Enable, Frequency Control, Power Good, Soft Start, Tracking. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. Switching converters are designed with the terminal (s) at position QUAD . Various 38 terminations. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 12V. Searching "LTC3859" will return other relevant dc to dc converter ics. Switching converter type is specifically Switching Regulator or Controllers. It is recommended to use 4.5V as the minimum input voltage of dc dc voltage regulator.
