LTC3859AMPFE#TRPBF Product Details

LTC3859AMPFE#TRPBF Overview


This switching controller fits most application requirements since it is packaged in a 38-TFSOP (0.173, 4.40mm Width) Exposed Pad package. 3 outputs can be generated with the dc motor controller. PMIC is packaged in a solid enclosure of Tape & Reel (TR). Transistor Driver dc switching's outputs (s) are supported. 4.5V~38V is the operating voltage and supply voltage of the dc control. Suitable for a -55°C~150°C TJ dc switcher. There is a switch at 115kHz~835kHz 350kHz~535kHz that can be used with this controller. dc dc regulator is made easier with Surface Mount. Enable, Frequency Control, Power Good, Soft Start, Tracking is used for efficient switching control in the dcdc regulator. An analog IC DUAL SWITCHING CONTROLLER is connected to the switch converters. The switching converters's terminal (s) are designed at DUAL . A variety of terminations with 38 of dc switching. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. DC switcher's input voltageis set to 12V. You can find other relevant dc to dc converter ics by searching "LTC3859". In particular, switching converter belongs to the Switching Regulator or Controllers family. dc dc voltage regulators should have a minimum input voltage of 4.5V. DC regulator outputs 5.4V voltage according to the test statistics.
