LTC3859AIFE#TRPBF Overview
The switching controller fits in the 38-TFSOP (0.173, 4.40mm Width) Exposed Pad package and is ideal for most applications. 3 outputs can be generated with the dc motor controller. The pmic is packaged in Tape & Reel (TR) solid enclosure. There are Transistor Driver dc switching's output (s) that it can handle. dc controls with 4.5V~38V voltage are supplied and operated. Suitable for working in an dc switcher that has a -40°C~125°C TJ. A switching controller such as this can switch at a value of 115kHz~835kHz 350kHz~535kHz . dc dc regulator can be generalized using Surface Mount. Switching control is made easier with the dcdc regulator's Enable, Frequency Control, Power Good, Soft Start, Tracking. Switch converters are connected to ICs with DUAL SWITCHING CONTROLLER analog outputs. Thare switching converters has a terminal (s) at DUAL . Various 38 terminations. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. DC switcher's input voltageis set to 12V. Other relevant dc to dc converter ics will be returned if you search "LTC3859". Switching converter is a type of Switching Regulator or Controllers in particular. 4.5V should be the minimum input voltage for the dc dc voltage regulator. Based on the test statistics, DC regulator outputs voltage 5.4V.
