LM5642XMT Overview

In the 28-TSSOP (0.173, 4.40mm Width) package, the switching controller meets most application requirements. There is sufficient capacity to generate switching controller for outputs 2. An enclosure of Tube is used to package the PMIC. There are Transistor Driver dc switching's output (s) that it can handle. 4.5V~36V is the supply voltage and the operating voltage of the dc control. Suitable for work in a -40°C~125°C TJ dc switcher. dc dc regulator is made easier with Surface Mount. In order to control switching efficiently, the dcdc regulator features Current Limit, Enable, Soft Start. An analog IC with the DUAL SWITCHING CONTROLLER signal is connected to the switch converters. Switching converters are designed with the terminal (s) at position DUAL . There are many different types of terminations for 28. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 5V is input. Other relevant dc to dc converter ics can be found by searching "LM5642". There are only 28 pins on switching converter. Specially, switching converter corresponds to type Switching Regulator or Controllers. A 32.4V voltage of DC regulator was detected in the test statistics. A starting point for a project is to note down the dc dc regulator's usual output current, which is 20A. A duty cycle set at 98.9 % ensures voltage regulator dc to dc reliability during power-on and power-off. As DC switcher has a Surface Mount, it's suitable for most applications and prototype designs. A frequency of 375kHz is set for the switching controller. In dormant mode, 1.1mA is used. In order to ensure the dc switcher's functionality, users must limit the voltage to 36V due to the dc switcher's maximum input voltage. Voltage 4.5V is needed for the supply. An output current greater than 20A cannot be provided by the dc switcher. The switching converter can output 32.4V volts at its utmost, according to the datasheet. 1.3V voltage output is lower than 1.3V.
