UC3844DX Overview
As a result of 14-SOIC (0.209, 5.30mm Width) compact design, the switching controller is compatible with most applications. This dc motor controller can be used to generate outputs with 1 numbers. Tape & Reel (TR) is the solid enclosure in which PMIC is packaged. With Transistor Driver dc switching's output (s), it is able to handle it. A 10V~30V voltage is supplied to the dc control and used for operating it. Work well in dc switchers with a 0°C~70°C TA. With this switching controller, you can switch at Up to 500kHz. As it has a Surface Mount value, it can be used for general dc dc regulator. Frequency Control is used for efficient switching control in the dcdc regulator. UC3844 can be used to locate other relevant dc to dc converter ics. There are a total of 14 pins on switching converter. normally, the dc dc regulator's output current is 1A, which you should keep in mind when starting a project. As a result of this, the maximum duty cycle of the voltage regulator dc to dc must remain 50 % during power-up and power-down. In most applications and prototypes, DC switcher's Surface Mount makes it suitable. A frequency of 500kHz is used by the switching controller. A supply current of 17mA is used to power it. There is 17mA nominal current supply for this the controllers dc.
