LX1684CD Overview


As a result of 14-SOIC (0.154, 3.90mm Width) compact design, the switching controller is compatible with most applications. For outputs of 1, this dc motor controller is suitable. The program can handle Transistor Driver dc switching's outputs (s). A 0°C~70°C TA dc switcher is not a problem. Using this switching controller, it is possible to switch at 175kHz. The Surface Mount allows it to be used for dc dc regulator in general. Current Limit, Soft Start is used for efficient switching control in the dcdc regulator. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. The switching converters's terminal (s) are designed at DUAL . Different dc switching's functions can be applied to 14 terminations. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. DC switcher's voltage input of 5V. LX1684 can be searched for other relevant dc to dc converter ics. Pins number 14 of switching converter in total. Because of DC switcher's Surface Mount, it is suitable for most prototype designs and applications. Switching controller operates at 200kHz Hz. When running the voltage regulator dc to dc in a circuit, users should apply 5V to ensure safety and reliability. A maximum value of 1A is output for current.
