LT3840MPFE#PBF Overview

Capsuled in the 28-TSSOP (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 1. PMIC is packaged in a solid enclosure of Tube. Transistor Driver dc switching's outputs (s) can be handled by it. 2.5V~60V is the operating voltage and supply voltage of the dc control. Qualified to work in a -55°C~150°C TJ dc switcher. A switching controller such as this can switch at a value of 50kHz~1MHz . The Surface Mount value makes it suitable for general dc dc regulator. Enable, Frequency Control, Power Good, Soft Start, Tracking provides dcdc regulator efficient switching control. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. switching converters terminal (s) are designed to be at DUAL. 28 terminations with various dc switching's functions. You can find other relevant dc to dc converter ics by searching "LT3840". dc dc voltage regulators should have a minimum input voltage of 2.5V. The dc to dc regulator can only accept 60V input voltage.
