LM5642XMTX/NOPB Product Details
LM5642XMTX/NOPB 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 Tape & Reel (TR) 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. This switching controller can switch at 375kHz. 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. The minimum input voltage of the dc dc voltage regulator should be 4.5V. According to the test statistics, DC regulator outputs 32.4V voltage. It should be fully noted that the dc to dc regulator only accepts 36V input voltage at most. 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 max frequency of the pmic can reach 424kHz. The dc switching utilizes 1.1mA when it is in a dormant state.
