LM5642MH/NOPB Overview


In the 28-PowerTSSOP (0.173, 4.40mm Width) package, the switching controller meets most application requirements. For outputs of 2, this dc motor controller is suitable. The pmic is packaged in Tube solid enclosure. Transistor Driver dc switching's outputs (s) are supported. 4.5V~36V is the supply voltage and the operating voltage of the dc control. Work well in dc switchers with a -40°C~125°C TJ. The Surface Mount makes it ideal for general dc dc regulator. In order to control switching efficiently, the dcdc regulator features Current Limit, Enable, Soft Start. A DUAL SWITCHING CONTROLLER analog IC is connected to the switch converters. There are a DUAL terminal on the switching converters. 28 terminations with various dc switching's functions. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. It is inputted with a DC switcher's voltage of 5V. Searching "LM5642" will return other relevant dc to dc converter ics. There are 28 pins on switching converter. According to the test statistics, DC regulator outputs 32.4V voltage. It's important to remember that the dc dc regulator's normaloutput current is 20A, so you should note it down when starting a new project. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 98.9 %. Having a Surface Mount makes DC switcher suitable for most application and prototype designs. A frequency of 200kHz is used by the switching controller. A dc switching in a dormant state uses 1.1mA. A nominal working status is achieved when the input voltage is set to 28V. The maximum input voltage of the dc switcher is 36V, so users need to limit the voltage accordingly. A voltage of 4.5V is required for the supply. Datasheets indicate that the switching converter can output 32.4V volts at its maximum. There is 1.3V voltage output lower than 1.3V on the voltage controller.
