LX1671CPW Overview


As a result of 38-TFSOP (0.173, 4.40mm Width) compact design, the switching controller is compatible with most applications. dc motor controller is suitable for 4 output generation. Transistor Driver dc switching's outputs (s) can be handled by it. DC control operates at 4.5V~5.5V volts and has 4.5V~5.5V supply voltage. Work well in dc switchers with a 0°C~70°C TA. It is suitable for general dc dc regulator when it is set to Surface Mount. DCDC regulator is controlled efficiently by Current Limit, Enable, Soft Start. An analog IC SWITCHING CONTROLLER is connected to the switch converters. DUAL are the position of the terminal of the switching converters. 38 terminations with various dc switching's functions. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 5V is input. You can find other relevant dc to dc converter ics by searching "LX1671". There are only 38 pins on switching converter. Specially, switching converter corresponds to type Switching Regulator or Controllers. Test statistics indicate DC regulator outputs 5.5V voltage. This Surface Mount makes DC switcher suitable for most prototypes and applications. Switching controller operates at 300kHz Hz. 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. Current is output to the greatest value of 1A. It belongs to the dc to dc voltage regulator series LoadSHARE?.
