LM5642XMT Product Details
LM5642XMT Overview
Capsuled in the 28-TSSOP (0.173, 4.40mm Width) package, the switching controller suits most application needs. The dc motor controller is adquate to generate for 2 outputs. The pmic is packaged in Tube solid enclosure. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sThe supply and operating voltage of the dc control are 4.5V~36V. Qualified to work in a -40°C~125°C TJ dc switcher. Surface Mount makes it suitable for general dc dc regulator. The dcdc regulator features Current Limit, Enable, Soft Start for efficient switching control. The switch converters are connected to a DUAL SWITCHING CONTROLLER analog IC. Terminal (s) of the switching converters are designed at the DUAL position. 28 terminations with a variety of function. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. 5V nominal DC switcher's voltage input. Other relevant dc to dc converter ics can be found by searching "LM5642". Switching converter has a total of 28 pins. Switching converter is a type of Switching Regulator or Controllers in particular. According to the test statistics, DC regulator outputs 32.4V voltage. The dc dc regulator's usual output current is 20A, which should be noted down when you start a project. To ensure the reliability under power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set as 98.9 %. DC switcher's Surface Mount makes it qualified for most application and prototype designs. DC switcher'sThe switching controller works at a frequency of 375kHz. The dc switching utilizes 1.1mA when it is in a dormant state. Because the dc switcher's maximum input voltage is 36V users must limit the voltage accordingly. Switching controller is necessary to have a supply voltage of 4.5V. The dc switcher will not provide an output current greater than 20A. The switching converter can output 32.4V volts at its utmost, according to the datasheet. The voltage controller's lowest voltage output is not less than 1.3V.
