UC2845ADTR Overview
It comes in a 14-SOIC (0.154, 3.90mm Width) package, so switching controller can be used for most applications. There is sufficient capacity to generate switching controller for outputs 1. Tape & Reel (TR) solid enclosure protects the pmic. Transistor Driver dc switching's outputs (s) can be handled by it. dc controls with 7.6V~30V voltage are supplied and operated. Suitable for a -40°C~85°C TA dc switcher. In this switching controller, the switch can be set to 500kHz. dc dc regulators can be carried out with Surface Mount. Frequency Control provides dcdc regulator 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. 14 terminations with various dc switching's functions. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 15V is input. Other relevant dc to dc converter ics will be returned if you search "UC2845". Switching converter has a total of 14 pins. Specially, switching converter corresponds to type Switching Regulator or Controllers. According to the test statistics, DC regulator outputs 15V voltage. If you are starting a new project, you should note the dc dc regulator's typical output current is 200mA. To ensure the reliability under power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set as 50 %. 450kHz is the frequency of the switching controller. It is possible to set the input voltage to 25V for nominal working status. The supply voltage should be 11V. A controller's current should not exceed 25mA.
