LTC3859ALEFE#TRPBF Overview


In the 38-TFSOP (0.173, 4.40mm Width) Exposed Pad package, the switching controller meets most application requirements. For 3 outputs, the dc motor controller is appropriate. Packaged in solid enclosures, this pmic has a Tape & Reel (TR) rating. Transistor Driver dc switching's outputs (s) can be handled by it. This dc control has a supply voltage and operating voltage of 4.5V~38V. Suitable for working in an dc switcher that has a -40°C~125°C TJ. With this switching controller, you can switch at 115kHz~835kHz 350kHz~535kHz. As it has a Surface Mount value, it can be used for general dc dc regulator. For efficient switching control, the dcdc regulator features Enable, Frequency Control, Power Good, Soft Start, Tracking. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. switching converters terminal (s) are designed to be at DUAL. Various 38 terminations. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. DC switcher's voltage input of 12V. You can find other relevant dc to dc converter ics by searching "LTC3859". Switching converter is a special type of Switching Regulator or Controllers. It is recommended to use 4.5V as the minimum input voltage of dc dc voltage regulator.
