    Products Detail

    E-L5991AD Overview


    This switching controller fits most application requirements since it is packaged in a 16-SOIC (0.154, 3.90mm Width) package. 1 outputs can be generated with the dc motor controller. PMIC is packaged in a solid enclosure of Tube. Transistor Driver dc switching's outputs (s) are supported. 7.6V~20V is the operating voltage and supply voltage of the dc control. Suitable for a -40°C~150°C TJ dc switcher. There is a switch at Up to 1MHz that can be used with this controller. dc dc regulator is made easier with Surface Mount. Current Limit, Frequency Control, Soft Start is used for efficient switching control in the dcdc regulator. An analog IC SWITCHING CONTROLLER is connected to the switch converters. The switching converters's terminal (s) are designed at DUAL . A variety of terminations with 16 of dc switching. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. DC switcher's input voltageis set to 15V. You can find other relevant dc to dc converter ics by searching "L5991". There are only 16 pins on switching converter. DC regulator outputs 5.075V voltage according to the test statistics. normally, the dc dc regulator's output current is 1.5A, which you should keep in mind when starting a project. voltage regulator dc to dcs with a 93 % duty cycle are designed to be reliable when powered on and powered off. Having a Surface Mount makes DC switcher ideal for most prototype and application designs. DC regulator's maximum frequency is 1MHz. When the dc switching is dormant, it uses 9mA.
