UC2845BD1G Overview
Capsuled in the 8-SOIC (0.154, 3.90mm Width) package, the switching controller can be used for a wide range of applications. For outputs of 1, this dc motor controller is suitable. Tube is the solid enclosure in which PMIC is packaged. The system can process Transistor Driver dc switching's outputs (s). This dc control has a supply voltage and operating voltage of 7.6V~30V. Qualified to work in an dc switcher with -25°C~85°C TA. Switching can be done at 500kHz with this switching controller. The Surface Mount allows it to be used for dc dc regulator in general. The dcdc regulator features Frequency Control for efficient switching control. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. Terminal (s) of the switching converters are designed at the DUAL position. Various 8 terminations. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 15V. UC284*B can be used to locate other relevant dc to dc converter ics. 8 pins are present on switching converter. The type is a particular Switching Regulator or Controllers of switching converter. Test statistics indicate DC regulator outputs 13.4V voltage. Voltages 25V are the maximum that the dc to dc regulator will accept. You should note down the dc dc regulator's usual output current of 12mA when you start a project. The duty cycle of the voltage regulator dc to dc can be set to 48 % on power-up or power-down to ensure reliability. Because of DC switcher's Surface Mount, it is suitable for most prototype designs and applications. Switching controller operates at 250kHz Hz. Components may become damaged if their current exceeds 17mA.
