LTC1922EN-1#PBF Overview


The switching controller fits in the 20-DIP (0.300, 7.62mm) package and is ideal for most applications. For outputs of 1, this dc motor controller is suitable. A solid enclosure of Tube surrounds pmic. With Transistor Driver dc switching's output (s), it is able to handle it. A 3.8V~10.3V voltage is supplied to the dc control and used for operating it. Qualified to work in a -40°C~85°C TA dc switcher. A switching controller such as this can switch at a value of Up to 1MHz . As it has a Through Hole value, it can be used for general dc dc regulator. For efficient switching control, the dcdc regulator features Ramp, Soft Start. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. Terminal (s) of the switching converters are designed at the DUAL position. The 20 terminations can be used for a wide range of dc switching. To name a few of the control techniques these dc dc converter ics adapt, it includes PHASE-SHIFT CONTROL. DC switcher's voltage input of 9.5V. A search for "LTC1922" will reveal other relevant dc to dc converter ics. The switching converter has a total of 20 pins. Particularly, switching converter is a type of Switching Regulator or Controllers. Statistically, DC regulator outputs 5V volts. A starting point for a project is to note down the dc dc regulator's usual output current, which is 100A. It is estimated that this dc regulatorhas a maximum frequency of 1MHz. This value is ALSO CONFIGURABLE IN CURRENT MODE so that DC to DC voltage regulator better serves the purpose.
