LTC3772ETS8#TRMPBF Overview
With its SOT-23-8 Thin, TSOT-23-8 package, the switching controller fits the needs of most applications. The pmic is packaged in Tape & Reel (TR) solid enclosure. It is capable of handling Transistor Driver dc switching's outputs (s). A 2.75V~9.8V voltage is supplied to the dc control and used for operating it. Qualified to work in an dc switcher with -40°C~85°C TA. Switching can be done at 550kHz with this switching controller. It is suitable for general dc dc regulator when it is set to Surface Mount. To provide efficient switching control, Current Limit, Enable is included in the dcdc regulator. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. There are a terminal (s) on the switching converters that are designed at DUAL. A variety of dc switching's functions can be performed on 8 terminations. The DC switcher's nominal voltage is 4.2V. You can find other relevant dc to dc converter ics by searching "LTC3772". The switching converter has a total of 8 pins. It is recommended that the input voltage of the dc dc voltage regulator be 2.75V. A duty cycle set at 100 % ensures voltage regulator dc to dc reliability during power-on and power-off. DC regulator's maximum frequency is 650kHz. 1A is the greatest value switching converter outputs as current. With this controller, the phase is 1.
