E-L5991AD Overview
It comes in a 16-SOIC (0.154, 3.90mm Width) package, so switching controller can be used for most applications. 1 outputs can be generated with the dc motor controller. Tube solid enclosure protects the pmic. The system can process Transistor Driver dc switching's outputs (s). Voltages 7.6V~20V are the dc control's supply voltage and operating voltage, respectively. Worked in a -40°C~150°C TJ dc switcher before. Using this switching controller, it is possible to switch at Up to 1MHz. As it has a Surface Mount value, it can be used for general dc dc regulator. In order to control switching efficiently, the dcdc regulator features Current Limit, Frequency Control, Soft Start. The switch converters are connected to a SWITCHING CONTROLLER analog IC. There are a DUAL terminal on the switching converters. An array of 16 terminations of dc switching. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. DC switcher's input voltageis 15V volts. You can find other relevant dc to dc converter ics by searching "L5991". There are only 16 pins on switching converter. Statistically, DC regulator outputs 5.075V volts. You should note that the dc dc regulator's usual output current is 1.5A. Voltage regulator dc to dc is designed to operate at 93 % duty cycle during power-ups and power-downs to ensure reliability. Having a Surface Mount makes DC switcher ideal for most prototype and application designs. There is a maximum frequency of 1MHz on this dc regulators. During dormancy, the dc switching uses 9mA.
