LM5642XMTX/NOPB Overview

It comes in the 28-TSSOP (0.173, 4.40mm Width) package, which makes switching controller suitable for most applications. There is sufficient capacity to generate switching controller for outputs 2. Packaged in solid enclosures, this pmic has a Tape & Reel (TR) rating. Transistor Driver dc switching's outputs (s) can be handled by it. Voltages 4.5V~36V are the dc control's supply voltage and operating voltage, respectively. Suitable for working in an dc switcher that has a -40°C~125°C TJ. It can switch at 375kHz. The Surface Mount value makes it suitable for general dc dc regulator. The dcdc regulator features Current Limit, Enable, Soft Start for efficient switching control. An analog IC with the DUAL SWITCHING CONTROLLER signal is connected to the switch converters. A switching converters's terminal (s) sits at the DUAL position. Different dc switching's functions can be applied to 28 terminations. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 5V. Other relevant dc to dc converter ics can be found by searching "LM5642". 28 pins are on switching converter. It is recommended that the input voltage of the dc dc voltage regulator be 4.5V. As determined by the test statistics, the output voltage of DC regulator is 32.4V. The dc to dc regulator can only accept a maximum input voltage of 36V. 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. Having a Surface Mount makes DC switcher ideal for most prototype and application designs. DC regulator424kHz has the maximum frequency. DC switching uses 1.1mA when it is dormant.
