    Products Detail

    L5991A Overview


    With its 16-DIP (0.300, 7.62mm) package, the switching controller fits the needs of most applications. For outputs of 1, this dc motor controller is suitable. Tube solid enclosure protects the pmic. It is capable of handling Transistor Driver dc switching's outputs (s). This dc control operates at 7.6V~20V and has a 7.6V~20V supply voltage. Worked in a -40°C~150°C TJ dc switcher before. In this switching controller, the switch can be set to Up to 1MHz. The Through Hole allows it to be used for dc dc regulator in general. In order to control switching efficiently, the dcdc regulator features Current Limit, Frequency Control, Soft Start. SWITCHING CONTROLLER analog IC connects the switch converters. Switching converters are designed with the terminal (s) at position DUAL . The 16 terminations can be used for a wide range of dc switching. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 15V is input. Searching "L5991" will return other relevant dc to dc converter ics. 16 pins are on switching converter. There is a particular type of Switching Regulator or Controllers in switching converter. Based on the test statistics, DC regulator outputs voltage 5.075V. If you are starting a new project, you should note the dc dc regulator's typical output current is 1.5A. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 93 %. In most applications and prototype designs, DC switcher is qualified as a Through Hole. There is a maximum frequency of 1MHz on this dc regulators.
