LM5642XMT/NOPB Overview
In the 28-TSSOP (0.173, 4.40mm Width) package, the switching controller meets most application requirements. This dc motor controller can be used to generate outputs with 2 numbers. Packaged in solid enclosures, this pmic has a Tube rating. With this function, you can deal with Transistor Driver dc switching's outputs (s). dc controls with 4.5V~36V voltage are supplied and operated. Suitable for a -40°C~125°C TJ dc switcher. This switching controller can switch at 375kHz. As it has a Surface Mount value, it can be used for general dc dc regulator. Switching control is made easier with the dcdc regulator's Current Limit, Enable, Soft Start. An analog IC with the DUAL SWITCHING CONTROLLER signal is connected to the switch converters. The switching converters's terminals (s) are designed at DUAL. An array of 28 terminations of dc switching. This dc dc converter ic uses 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". There are a total of 28 pins on switching converter. Statistically, the DC regulator outputs 32.4V voltage. normally, the dc dc regulator's output current is 20A, which you should keep in mind when starting a project. 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. It is estimated that this dc regulatorhas a maximum frequency of 424kHz. DC switching uses 1.1mA when it is dormant. 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. 4.5V is the required supply voltage. A datasheet states that the switching converter can output 32.4V volts at its maximum. The voltage controller's lowest voltage output is not less than 1.3V.
