LT3840MPFE#TRPBF Overview


Capsuled in the 28-TSSOP (0.173, 4.40mm Width) Exposed Pad package, the switching controller suits most application needs. The dc motor controller is adquate to generate for 1 outputs. Tape & Reel (TR) solid enclosure protects the pmic. Transistor Driver dc switching's outputs (s) are supported. This dc control operates at 2.5V~60V and has a 2.5V~60V supply voltage. Worked in a -55°C~150°C TJ dc switcher before. Using this switching controller, it is possible to switch at 50kHz~1MHz. The Surface Mount makes it ideal for general dc dc regulator. The dcdc regulator features Enable, Frequency Control, Power Good, Soft Start, Tracking for efficient switching control. An analog IC SWITCHING CONTROLLER is connected to the switch converters. Thare switching converters has a terminal (s) at DUAL . 28 terminations with various dc switching's functions. Searching "LT3840" will return other relevant dc to dc converter ics. An input voltage of 2.5V is the minimum required for the dc dc voltage regulator. Voltages 60V are the maximum that the dc to dc regulator will accept.
