UC2845BDG Overview
In the 14-SOIC (0.154, 3.90mm Width) package, the switching controller meets most application requirements. 1 outputs are supported by the dc motor controller. Packaged in solid enclosures, this pmic has a Tube rating. There are Transistor Driver dc switching's output (s) that it can handle. This dc control operates at 7.6V~30V and has a 7.6V~30V supply voltage. Qualified to work in a -25°C~85°C TA dc switcher. With this switching controller, you can switch at 500kHz. The Surface Mount value makes it suitable for general dc dc regulator. Featured in the dcdc regulator is Frequency Control which allows efficient switching control. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. A switching converters's terminal (s) sits at the DUAL position. Various 14 terminations. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 15V. Search for "UC284*B" to find other relevant dc to dc converter ics. There are 14 pins on switching converter. Switching converter is a special type of Switching Regulator or Controllers. The test statistics indicate that DC regulator outputs a voltage of 5.05V. Considering the dc to dc regulator can only accept 25V input voltage, it is important to take note of this. The dc dc regulator's usual output current is 1kA, which should be noted down when you start a project. A duty cycle set at 48 % ensures voltage regulator dc to dc reliability during power-on and power-off. Having a Surface Mount makes DC switcher ideal for most prototype and application designs. DC regulator275kHz has the maximum frequency. The component might suffer damage if the current exceeds 17mA.
