UC3845BVD1G Overview
Capsuled in the 8-SOIC (0.154, 3.90mm Width) package, the switching controller suits most application needs. There is sufficient capacity to generate switching controller for outputs 1. Tube is the solid enclosure in which PMIC is packaged. Transistor Driver dc switching's outputs (s) are supported. Voltages 7.6V~30V are the dc control's supply voltage and operating voltage, respectively. A -40°C~105°C TA dc switcher is not a problem. With this switching controller, you can switch at 500kHz. The Surface Mount makes it ideal for general dc dc regulator. Frequency Control is used for efficient switching control in the dcdc regulator. The switch converters are connected to a SWITCHING CONTROLLER analog IC. There are a DUAL terminal on the switching converters. An array of 8 terminations of dc switching. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. DC switcher's input voltageis 15V volts. Other relevant dc to dc converter ics can be found by searching "UC384*B". In total, switching converter has 8 pins. In particular, switching converter belongs to the Switching Regulator or Controllers family. Test statistics indicate DC regulator outputs 13.4V voltage. Voltages 25V are the maximum that the dc to dc regulator will accept. If you are starting a new project, you should note the dc dc regulator's typical output current is 200mA. As a result of this, the maximum duty cycle of the voltage regulator dc to dc must remain 48 % during power-up and power-down. In most applications and prototypes, DC switcher's Surface Mount makes it suitable. Switching controllers work at 52kHz Hz. There is a possibility that a current higher than 17mA will cause improper operation of the component and possibly damage switching voltage regulators.
