UC3845BD1013TR Overview


Capsuled in the 8-SOIC (0.154, 3.90mm Width) package, the switching controller suits most application needs. For outputs of 1, this dc motor controller is suitable. Tape & Reel (TR) solid enclosure protects the pmic. The program can handle Transistor Driver dc switching's outputs (s). 7.6V~30V is the supply voltage and the operating voltage of the dc control. Qualified to work in an dc switcher with -40°C~150°C TJ. The Surface Mount allows it to be used for dc dc regulator in general. To provide efficient switching control, Frequency Control is included in the dcdc regulator. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. Switching converters are designed with the terminal (s) at position DUAL . The 8 terminations can be used for a wide range of dc switching. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. 15V nominal DC switcher's voltage input. Searching "UC3845" will return other relevant dc to dc converter ics. 8 pins are present on switching converter. Switching converter is a type of Switching Regulator or Controllers in particular. Statistically, the DC regulator outputs 5.1V voltage. If you start a project, note down the dc dc regulator's usual output current of 1A. voltage regulator dc to dcs with a 50 % duty cycle are designed to be reliable when powered on and powered off. Having a Surface Mount makes DC switcher ideal for most prototype and application designs. Switching controllers operate at 500kHz frequencies. The dc switching utilizes 12mA when it is in a dormant state. Input voltage can be set to 30V for nominal working status. Continually operating at more than 12mA may cause malfunctions and damage to the component.
