RT9258GQW Overview
This switching controller fits most application requirements since it is packaged in a 24-WFQFN Exposed Pad package. It is sufficient to generate 2 outputs with this dc motor controller. PMIC is packaged in a solid enclosure of Tape & Reel (TR). Transistor Driver dc switching's outputs (s) are supported. This dc control has a supply voltage and operating voltage of 10.8V~13.2V. A -40°C~85°C TA dc switcher is not a problem. Using this switching controller, it is possible to switch at 500kHz. The Surface Mount value makes it suitable for general dc dc regulator. To provide efficient switching control, Current Limit, Enable, Frequency Control, Phase Control, Power Good, Soft Start is included in the dcdc regulator. The switching converters's terminal (s) are designed at QUAD . An array of 24 terminations of dc switching. Switching converter is a type of Switching Regulator or Controllers in particular. The maximum duty cycle of this voltage regulator dc to dc is set to 75 % to ensure reliability during power-up and power-down.
