LM27403SQ/NOPB Overview

This switching controller fits most application requirements since it is packaged in a 24-WFQFN Exposed Pad package. For outputs of 1, this dc motor controller is suitable. A solid enclosure of Tape & Reel (TR) surrounds pmic. A total of Transistor Driver dc switching's outputs can be handled by it. This dc control has a supply voltage and operating voltage of 3V~20V. Worked in a -40°C~125°C TJ dc switcher before. The switching controller is capable of switching at the 200kHz~1.2MHz position. Surface Mount makes it suitable for general dc dc regulator. DCDC regulator is controlled efficiently by Enable, Frequency Control, Power Good, Soft Start, Tracking. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. Terminal (s) of the switching converters are designed at the QUAD position. A variety of terminations with 24 of dc switching. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 12V. Search for "LM27403" to find other relevant dc to dc converter ics. 24 pins are present on switching converter. The test statistics indicate that DC regulator outputs a voltage of 4.7V. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 93 %. This Surface Mount makes DC switcher suitable for most prototypes and applications. For safe and reliable operation in a circuit, voltage regulator dc to dc is suggested that users apply 20V. In dormant mode, 3.5mA is used. The maximum input voltage of dc switcher is 20V, so users should limit their voltage accordingly. A voltage of 3V is required for the supply. Output current will not exceed 15A. Its datasheet indicates the switching converter can output a maximum of 19V volts. There is 3.5mA supply current for it. Lowest voltage output of the voltage controller must be greater than 600mV.
