ISL6557ACB Overview

The switching controller fits in the 24-SOIC (0.295, 7.50mm Width) package and is ideal for most applications. dc motor controller is suitable for 4 output generation. Packaged in solid enclosures, this pmic has a Tube rating. There are PWM Signal dc switching's output (s) that it can handle. A 4.75V~5.25V voltage is supplied to the dc control and used for operating it. Suitable for work in a 0°C~70°C TA dc switcher. With this switching controller, you can switch at 80kHz~1.5MHz. The Surface Mount makes it ideal for general dc dc regulator. Featured in the dcdc regulator is Current Limit, Enable, Power Good which allows efficient switching control. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. There are a terminal (s) on the switching converters that are designed at DUAL. 24 terminations with various dc switching's functions. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. The DC switcher's nominal voltage is 5V. Considering the dc to dc regulator can only accept 5.25V input voltage, it is important to take note of this. In order to satisfy the need, DC to DC voltage regulator has a value of IT CAN ALSO OPERATE WITH CURRENT MODE.
