ISL6557ACB-T Overview
It comes in the 24-SOIC (0.295, 7.50mm Width) package, which makes switching controller suitable for most applications. It is sufficient to generate 4 outputs with this dc motor controller. Packaging for the pmic consists of Tape & Reel (TR) solid enclosures. With this function, you can deal with PWM Signal dc switching's outputs (s). This dc control has a supply voltage and operating voltage of 4.75V~5.25V. Qualified to work in an dc switcher with 0°C~70°C TA. Using this switching controller, it is possible to switch at 80kHz~1.5MHz. The Surface Mount allows it to be used for dc dc regulator in general. Switching control is made easier with the dcdc regulator's Current Limit, Enable, Power Good. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. Terminal (s) of the switching converters are designed at the DUAL position. 24 terminations with a variety of function. 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 5V. You can find other relevant dc to dc converter ics by searching "ISL6557A". At most, the dc to dc regulator accepts 5.25V input voltage.
