LM5027ASQ/NOPB Product Details

LM5027ASQ/NOPB Overview


It comes in the 24-WFQFN Exposed Pad package, which makes switching controller suitable for most applications. This dc motor controller can be used to generate outputs with 3 numbers. Packaging for the pmic consists of Tape & Reel (TR) solid enclosures. With this function, you can deal with Transistor Driver dc switching's outputs (s). This dc control has a supply voltage and operating voltage of 13V~90V. Suitable for work in a -40°C~125°C TJ dc switcher. Switching can be done at 310kHz with this switching controller. It is suitable for general dc dc regulator when it is set to Surface Mount. The dcdc regulator features Frequency Control, Ramp, Soft Start for efficient switching control. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. The switching converters's terminal (s) are designed at QUAD . A variety of dc switching's functions can be performed on 24 terminations. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. DC switcher's input voltageis set to 48V. LM5027 can be used to locate other relevant dc to dc converter ics. In total, switching converter has 24 pins. In particular, switching converter belongs to the Switching Regulator or Controllers family. DC regulator outputs 7.7V voltage based on test statistics. In most cases, the output current of the dc dc regulator will be 3A, so note that when you start the 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 75 %. In most applications and prototypes, DC switcher's Surface Mount makes it suitable. There is a maximum frequency of 1MHz for this dc regulators. To run the voltage regulator dc to dc safely and reliably, users should apply 90V to the voltage regulator dc to dc. There is 6.8mA supply current for it.
