LTC3859ALHFE#TRPBF Overview


Capsuled in the 38-TFSOP (0.173, 4.40mm Width) Exposed Pad package, the switching controller suits most application needs. The dc motor controller is adquate to generate for 3 outputs. The pmic is packaged in Tape & Reel (TR) solid enclosure. A total of Transistor Driver dc switching's outputs can be handled by it. DC control operates at 4.5V~38V volts and has 4.5V~38V supply voltage. Workable in an dc switcher where -40°C~150°C TJ is the -40°C~150°C TJrm. In this switching controller, the switch can be set to 115kHz~835kHz 350kHz~535kHz. dc dc regulators can be carried out with Surface Mount. DCDC regulator is controlled efficiently by Enable, Frequency Control, Power Good, Soft Start, Tracking. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. A switching converters's terminal (s) sits at the DUAL position. A variety of 38 terminations are available in dc switching. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. DC switcher's voltage input is 12V. LTC3859 can be searched for other relevant dc to dc converter ics. The type is a particular Switching Regulator or Controllers of switching converter. An input voltage of 4.5V is the minimum required for the dc dc voltage regulator.
