LX1672-05CPW Overview
Capsuled in the 28-TSSOP (0.173, 4.40mm Width) package, the switching controller can be used for a wide range of applications. 3 outputs are supported by the dc motor controller. With Transistor Driver dc switching's output (s), it is able to handle it. A 4.5V~5.5V voltage is supplied to the dc control and used for operating it. A 0°C~70°C TA dc switcher is not a problem. In this switching controller, the switch can be set to 500kHz. It is suitable for general dc dc regulator when it is set to Surface Mount. DCDC regulator is controlled efficiently by Current Limit, Soft Start. The switch converters are connected to an analog IC with a DUAL SWITCHING CONTROLLER output. DUAL are the position of the terminal of the switching converters. A variety of 28 terminations are available in dc switching. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 5V. Search for "LX1672" to find other relevant dc to dc converter ics. There are only 28 pins on switching converter. An input voltage of 4.5V is the minimum required for the dc dc voltage regulator. 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. A frequency of 575kHz is used by the switching controller. The dc to dc voltage regulator belongs to the LoadSHARE? series. There will be 1A current output from the dc switcher above 1A.
