LX1682IDM Product Details
LX1682IDM Overview
In the 8-SOIC (0.154, 3.90mm Width) package, the switching controller meets most application requirements. 1 outputs are supported by the dc motor controller. It is capable of handling Transistor Driver dc switching's outputs (s). Workable in an dc switcher where 0°C~70°C TA is the 0°C~70°C TArm. The switching controller can be switched at 190kHz. dc dc regulators can be carried out with Surface Mount. To provide efficient switching control, Current Limit, Soft Start is included in the dcdc regulator. A SWITCHING CONTROLLER analog IC is connected to the switch converters. Switching converters are designed with the terminal (s) at position DUAL . A variety of dc switching's functions can be performed on 8 terminations. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 5V. Search for "LX1682" to find other relevant dc to dc converter ics. There are 8 pins on switching converter. An input voltage of 4.4V is the minimum required for the dc dc voltage regulator. DC regulator outputs 4.5V voltage based on test statistics. Because of DC switcher's Surface Mount, it is suitable for most prototype designs and applications. A frequency of 230kHz is set for the switching controller. It is suggested that users apply 5V to the voltage regulator dc to dc in order to run it safely and reliably in a circuit. The output of this function is the greatest value of 1A.
