UC3844BDR2 Overview
In the 8-SOIC (0.154, 3.90mm Width) package, the switching controller meets most application requirements. There is sufficient capacity to generate switching controller for outputs 1. Tape & Reel (TR) is the solid enclosure in which PMIC is packaged. Transistor Driver dc switching's outputs (s) are supported. dc control's supply and operating voltages are 10V~36V. Workable in an dc switcher where 0°C~70°C TA is the 0°C~70°C TArm. The switching controller can be switched at Up to 500kHz. The Surface Mount value makes it suitable for general dc dc regulator. DCDC regulator is controlled efficiently by Frequency Control. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. The switching converters's terminals (s) are designed at DUAL. Various 14 terminations. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's input voltageis set to 15V. Other relevant dc to dc converter ics will be returned if you search "UC384*B". There are only 8 pins on switching converter. The type is a particular Switching Regulator or Controllers of switching converter. A 5.1V voltage of DC regulator was detected in the test statistics. Considering the dc to dc regulator can only accept 25V input voltage, it is important to take note of this. If you are starting a new project, you should note the dc dc regulator's typical output current is 1A. The duty cycle of the voltage regulator dc to dc can be set to 48 % on power-up or power-down to ensure reliability. Having a Surface Mount makes DC switcher ideal for most prototype and application designs.
