LTC3772EDDB#TRPBF Overview


This switching controller fits most application requirements since it is packaged in a 8-WFDFN Exposed Pad package. It is sufficient to generate 1 outputs with this dc motor controller. There is a Tape & Reel (TR) solid enclosure around the pmic. A total of Transistor Driver dc switching's outputs can be handled by it. dc control's supply and operating voltages are 2.75V~9.8V. Suitable for working in an dc switcher that has a -40°C~85°C TA. It can switch at 550kHz. dc dc regulator can be generalized using Surface Mount. Switching control is made easier with the dcdc regulator's Current Limit, Enable. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. Switching converters are designed with the terminal (s) at position DUAL . 8 terminations with various dc switching's functions. 4.2V nominal DC switcher's voltage input. You can find other relevant dc to dc converter ics by searching "LTC3772". Total pins of switching converter are 8. The minimum input voltage of the dc dc voltage regulator should be 2.75V. Statistically, DC regulator outputs 9.8V volts. It's important to remember that the dc dc regulator's normaloutput current is 5A, so you should note it down when starting a new project. 650kHz is the maximum frequency of this dc regulators.
