ISL6558IRZ-TK Overview
Capsuled in the 20-VQFN Exposed Pad package, the switching controller suits most application needs. It is sufficient to generate 4 outputs with this dc motor controller. A solid enclosure of Tape & Reel (TR) surrounds pmic. With this function, you can deal with PWM Signal dc switching's outputs (s). This dc control operates at 4.75V~5.25V and has a 4.75V~5.25V supply voltage. Worked in a -40°C~85°C TA dc switcher before. In this switching controller, the switch can be set to 80kHz~1.5MHz. The Surface Mount makes it ideal for general dc dc regulator. To ensure efficient switching, this dcdc regulator features a Enable, Frequency Control, Power Good. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. Thare switching converters has a terminal (s) at QUAD . 20 terminations with various dc switching's functions. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. DC switcher's input voltageis 5V volts. A search for "ISL6558" will reveal other relevant dc to dc converter ics. Voltages 5.25V are the maximum that the dc to dc regulator will accept.
