LM5642MTC Overview


This switching controller fits most application requirements since it is packaged in a 28-TSSOP (0.173, 4.40mm Width) package. There is enough capacity in the dc motor controller to generate the output for the 2 input. A solid enclosure of Tube surrounds pmic. With Transistor Driver dc switching's output (s), it is able to handle it. 4.5V~36V is the operating voltage and supply voltage of the dc control. Qualified to work in a -40°C~125°C TJ dc switcher. dc dc regulator can be generalized using Surface Mount. To ensure efficient switching, this dcdc regulator features a Current Limit, Enable, Soft Start. The switch converters are connected to an analog IC with a DUAL SWITCHING CONTROLLER output. Thare switching converters has a terminal (s) at DUAL . Various 28 terminations. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. DC switcher's voltage input is 5V. A search for "LM5642" will reveal other relevant dc to dc converter ics. Switching converter has a total of 28 pins. It is recommended that the input voltage of the dc dc voltage regulator be 4.5V. Statistically, the DC regulator outputs 32.4V voltage. Considering the dc to dc regulator can only accept 36V input voltage, it is important to take note of this. If you start a project, note down the dc dc regulator's usual output current of 20A. The duty cycle of the voltage regulator dc to dc can be set to 98.9 % on power-up or power-down to ensure reliability. This Surface Mount makes DC switcher suitable for most prototypes and applications. Switching controller operates at 200kHz Hz. The dc switching utilizes 1.1mA when it is in a dormant state.
