L5991AD Overview


As a result of 16-SOIC (0.154, 3.90mm Width) compact design, the switching controller is compatible with most applications. 1 outputs are supported by the dc motor controller. An enclosure of Tube is used to package the PMIC. The system can process Transistor Driver dc switching's outputs (s). 7.6V~20V is the supply voltage and the operating voltage of the dc control. Workable in an dc switcher where -40°C~150°C TJ is the -40°C~150°C TJrm. The switching controller is capable of switching at the Up to 1MHz position. dc dc regulator can be generalized using Surface Mount. Switching control is made easier with the dcdc regulator's Current Limit, Frequency Control, Soft Start. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. switching converters terminal (s) are designed to be at DUAL. There are many different types of terminations for 16. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. It is inputted with a DC switcher's voltage of 15V. A search for "L5991" will reveal other relevant dc to dc converter ics. 16 pins are present on switching converter. The type is a particular Switching Regulator or Controllers of switching converter. Statistically, the DC regulator outputs 5V voltage. It's important to remember that the dc dc regulator's normaloutput current is 1.5kA, so you should note it down when starting a new project. The maximum duty cycle of this voltage regulator dc to dc is set to 93 % to ensure reliability during power-up and power-down. As DC switcher has a Surface Mount, it's suitable for most applications and prototype designs. Switching controller operates at 1MHz Hz. It is possible to set the input voltage as 15V for nominal working statuses. There is a possibility that a current higher than 13mA will cause improper operation of the component and possibly damage switching voltage regulators.
