LM5642MTC/NOPB Overview
With its 28-TSSOP (0.173, 4.40mm Width) package, the switching controller fits the needs of most applications. There is enough capacity in the dc motor controller to generate the output for the 2 input. Packaging for the pmic consists of Tube solid enclosures. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sA 4.5V~36V voltage is supplied to the dc control and used for operating it. Worked in a -40°C~125°C TJ dc switcher before. There is a switch at 200kHz that can be used with this controller. It is suitable for general dc dc regulator when it is set to Surface Mount. For efficient switching control, the dcdc regulator features Current Limit, Enable, Soft Start. A DUAL SWITCHING CONTROLLER analog IC is connected to the switch converters. Switching converters are designed with the terminal (s) at position DUAL . 28 terminations with a variety of function. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 5V. LM5642 can be searched for other relevant dc to dc converter ics. 28 pins are present on switching converter. This dc dc voltage regulator should be powered by a voltage of 4.5V. Statistically, DC regulator outputs 32.4V volts. It should be noted that the dc to dc regulator only accepts 36V voltage as input voltage. If you are starting a new project, you should note the dc dc regulator's typical output current is 20mA. Voltage regulator dc to dc is designed to operate at 98.9 % duty cycle during power-ups and power-downs to ensure reliability. As DC switcher has a Surface Mount, it's suitable for most applications and prototype designs. There is a maximum frequency of 226kHz on this dc regulators. As long as the dc switching is in a dormant state, it utilizes 1.1mA.
