ISL6557ACB Overview


With its 24-SOIC (0.295, 7.50mm Width) package, the switching controller fits the needs of most applications. This dc motor controller can be used to generate outputs with 4 numbers. An enclosure of Tube is used to package the PMIC. The system can process PWM Signal dc switching's outputs (s). This dc control has a supply voltage and operating voltage of 4.75V~5.25V. Worked in an dc switcher with a 0°C~70°C TA rating. There is a switch at 80kHz~1.5MHz that can be used with this controller. As it has a Surface Mount value, it can be used for general dc dc regulator. Current Limit, Enable, Power Good provides dcdc regulator efficient switching control. The switch converters are connected to a SWITCHING CONTROLLER analog IC. switching converters terminal (s) are designed to be at DUAL. Various 24 terminations. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 5V is input. A search for "ISL6557A" will reveal other relevant dc to dc converter ics. The dc to dc regulator can only accept a maximum input voltage of 5.25V.
