LT8709EFE#PBF Overview


With its 20-TSSOP (0.173, 4.40mm Width) Exposed Pad package, the switching controller fits the needs of most applications. For outputs of 1, this dc motor controller is suitable. The pmic is packaged in Tube solid enclosure. Transistor Driver dc switching's outputs (s) are supported. This dc control has a supply voltage and operating voltage of -4.5V~-80V. Qualified to work in a -40°C~125°C TJ dc switcher. Using this switching controller, it is possible to switch at 100kHz~750kHz. Surface Mount makes it suitable for general dc dc regulator. To provide efficient switching control, Enable, Frequency Control, Power Good, Soft Start is included in the dcdc regulator. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. A switching converters's terminal (s) sits at the DUAL position. 20 terminations with a variety of function. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. A DC switcher's nominal voltage of -12V is input. Search for "LT8709" to find other relevant dc to dc converter ics. This dc dc voltage regulator should be powered by a voltage of -4.5V. A maximum voltage of -80V is accepted by the dc to dc regulator as an input voltage.
