LTC3859AIFE Overview
Capsuled in the 38-TFSOP (0.173, 4.40mm Width) Exposed Pad package, the switching controller suits most application needs. There is sufficient capacity to generate switching controller for outputs 3. An enclosure of Tube is used to package the PMIC. With this function, you can deal with Transistor Driver dc switching's outputs (s). dc controls with 4.5V~38V voltage are supplied and operated. Qualified to work in a -40°C~125°C TJ dc switcher. There is a switch at 115kHz~835kHz 350kHz~535kHz that can be used with this controller. Surface Mount makes it suitable for general dc dc regulator. Enable, Frequency Control, Power Good, Soft Start, Tracking is used for efficient switching control in the dcdc regulator. The switch converters are connected to a DUAL SWITCHING CONTROLLER analog IC. Switching converters are designed with the terminal (s) at position DUAL . 38 terminations with various dc switching's functions. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 12V. LTC3859 can be searched for other relevant dc to dc converter ics. Switching converter is a special type of Switching Regulator or Controllers. dc dc voltage regulators should have a minimum input voltage of 4.5V. The test statistics indicate that DC regulator outputs a voltage of 5.4V.
