LM5642XMH/NOPB Overview
With its 28-PowerTSSOP (0.173, 4.40mm Width) package, the switching controller fits the needs of most applications. There is enough capacity in the dc motor controller to generate the output for the 2 input. Packaged in solid enclosures, this pmic has a Tube rating. The system can process Transistor Driver dc switching's outputs (s). dc control's supply and operating voltages are 4.5V~36V. Qualified to work in an dc switcher with -40°C~125°C TJ. The switching controller is capable of switching at the 375kHz position. The Surface Mount allows it to be used for dc dc regulator in general. For efficient switching control, the dcdc regulator features Current Limit, Enable, Soft Start. A DUAL SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. There are a terminal (s) on the switching converters that are designed at DUAL. 28 terminations with a variety of function. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's input voltageis 5V volts. Other relevant dc to dc converter ics will be returned if you search "LM5642". 28 pins are present on switching converter. Test statistics indicate DC regulator outputs 32.4V voltage. You should note down the dc dc regulator's usual output current of 600mA when you start a project. As a result of this, the maximum duty cycle of the voltage regulator dc to dc must remain 98.9 % during power-up and power-down. As DC switcher has a Surface Mount, it's suitable for most applications and prototype designs. DC regulator's maximum frequency is 424kHz. During dormancy, the dc switching uses 1.1mA. Users must limit the voltage accordingly because the dc switcher's maximum input voltage is 36V. A voltage of 4.5V must be present in the supply. Depending on the datasheet, the switching converter can output 32.4V volts at its peak. At least 1.3V voltage is output by the voltage controller.
