LTC3859ALMPFE Overview
The switching controller fits in the 38-TFSOP (0.173, 4.40mm Width) Exposed Pad package and is ideal for most applications. It is sufficient to generate 3 outputs with this dc motor controller. There is a Tube solid enclosure around the pmic. There are Transistor Driver dc switching's output (s) that it can handle. dc controls with 4.5V~38V voltage are supplied and operated. Worked in a -55°C~150°C TJ dc switcher before. The switching controller can be switched at 115kHz~835kHz 350kHz~535kHz. Surface Mount makes it suitable for general dc dc regulator. DCDC regulator is controlled efficiently by Enable, Frequency Control, Power Good, Soft Start, Tracking. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. DUAL are the position of the terminal of the switching converters. The 38 terminations can be used for a wide range of dc switching. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. DC switcher's input voltageis 12V volts. LTC3859 can be searched for other relevant dc to dc converter ics. In particular, switching converter belongs to the Switching Regulator or Controllers family. Input voltage of dc dc voltage regulator must be 4.5V.
