LTC3859ALMPFE#PBF Overview
It comes in a 38-TFSOP (0.173, 4.40mm Width) Exposed Pad package, so switching controller can be used for most applications. dc motor controller is suitable for 3 output generation. A solid enclosure of Tube surrounds pmic. With Transistor Driver dc switching's output (s), it is able to handle it. 4.5V~38V is the supply voltage and the operating voltage of the dc control. Suitable for work in 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 regulators can be carried out with 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 SWITCHING CONTROLLER analog outputs. There are a DUAL terminal on the switching converters. A variety of dc switching's functions can be performed on 38 terminations. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. DC switcher's voltage input of 12V. Other relevant dc to dc converter ics can be found by searching "LTC3859". Switching converter is a special type of Switching Regulator or Controllers. An input voltage of 4.5V is the minimum required for the dc dc voltage regulator.
