LM5642MH/NOPB Product Details

LM5642MH/NOPB Overview


As a result of 28-PowerTSSOP (0.173, 4.40mm Width) compact design, the switching controller is compatible with most applications. 2 outputs are supported by the dc motor controller. An enclosure of Tube is used to package the PMIC. The system can process Transistor Driver dc switching's outputs (s). 4.5V~36V is the supply voltage and the operating voltage of the dc control. Workable in an dc switcher where -40°C~125°C TJ is the -40°C~125°C TJrm. dc dc regulator can be generalized using Surface Mount. Switching control is made easier with the dcdc regulator's Current Limit, Enable, Soft Start. Connected to a DUAL SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. switching converters terminal (s) are designed to be at DUAL. There are many different types of terminations for 28. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. It is inputted with a DC switcher's voltage of 5V. A search for "LM5642" will reveal other relevant dc to dc converter ics. 28 pins are present on switching converter. Statistically, the 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. The maximum duty cycle of this voltage regulator dc to dc is set to 98.9 % to ensure reliability during power-up and power-down. As DC switcher has a Surface Mount, it's suitable for most applications and prototype designs. Switching controller operates at 200kHz Hz. As long as the dc switching is in a dormant state, it utilizes 1.1mA. It is possible to set the input voltage as 28V for nominal working statuses. In order to limit the voltage of a dc switcher whose maximum input voltage is 36V, it must be limited by the user. Voltage 4.5V is necessary for the supply. At its maximum, the switching converter can output 32.4V volts. At its lowest voltage, the voltage controller does not produce less than 1.3V.
