LT1952EGN-1#PBF Product Details
LT1952EGN-1#PBF Overview
As a result of 16-SSOP (0.154, 3.90mm Width) compact design, the switching controller is compatible with most applications. dc motor controller is suitable for 1 output generation. Packaging for the pmic consists of Tube solid enclosures. A total of Transistor Driver dc switching's outputs can be handled by it. 6.82V~25V is the operating voltage and supply voltage of the dc control. Worked in an dc switcher with a -40°C~125°C TJ rating. A switching controller such as this can switch at a value of 100kHz~500kHz . Surface Mount makes it suitable for general dc dc regulator. In order to control switching efficiently, the dcdc regulator features Enable, Frequency Control. A SWITCHING CONTROLLER analog IC is connected to the switch converters. There are a DUAL terminal on the switching converters. 16 terminations with various dc switching's functions. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. DC switcher's input voltageis 15V volts. LT1952 can be used to locate other relevant dc to dc converter ics. Total pins of switching converter are 16. In particular, switching converter belongs to the Switching Regulator or Controllers family. Switching controllers operate at 200kHz frequencies. Whenever the current value is 1A, switching converter outputs the highest possible value. 25V is the nominal working voltage.
