LX1672-03CPW Overview
Capsuled in the 28-TSSOP (0.173, 4.40mm Width) package, the switching controller suits most application needs. The dc motor controller is adquate to generate for 3 outputs. There are Transistor Driver dc switching's output (s) that it can handle. This dc control has a supply voltage and operating voltage of 4.5V~5.5V. Qualified to work in a 0°C~70°C TA dc switcher. The switching controller can be switched at 300kHz. dc dc regulator can be generalized using Surface Mount. To ensure efficient switching, this dcdc regulator features a Current Limit, Soft Start. The switch converters are connected to an analog IC with a DUAL SWITCHING CONTROLLER output. Terminal (s) of the switching converters are designed at the DUAL position. The 28 terminations can be used for a wide range of dc switching. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's voltage input is 5V. You can find other relevant dc to dc converter ics by searching "LX1672". 28 pins are on switching converter. This dc dc voltage regulator should be powered by a voltage of 4.5V. The dc to dc regulator can only accept a maximum input voltage of 5.5V. In most applications and prototype designs, DC switcher is qualified as a Surface Mount. 345kHz is the frequency of the switching controller. A dc to dc voltage regulator in the LoadSHARE? series, it belongs to this family. In this case, the dc switcher won't produce more than 1A watts of output current.
