UC3844BVD Overview
It comes in a 14-SOIC (0.154, 3.90mm Width) package, so switching controller can be used for most applications. The dc motor controller is adquate to generate for 1 outputs. Packaged in solid enclosures, this pmic has a Tube rating. With this function, you can deal with Transistor Driver dc switching's outputs (s). dc controls with 10V~36V voltage are supplied and operated. Worked in an dc switcher with a -40°C~105°C TA rating. In this switching controller, the switch can be set to Up to 500kHz. Surface Mount makes it suitable for general dc dc regulator. To provide efficient switching control, Frequency Control is included in the dcdc regulator. The switch converters are connected to a SWITCHING CONTROLLER analog IC. Thare switching converters has a terminal (s) at DUAL . Different dc switching's functions can be applied to 14 terminations. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 15V. You can find other relevant dc to dc converter ics by searching "UC384*B". 14 pins are present on switching converter. The type is a particular Switching Regulator or Controllers of switching converter. Voltages 25V are the maximum that the dc to dc regulator will accept. DC switcher's Surface Mount qualifies it for most applications and prototypes. A frequency of 275kHz is used by the switching controller. A maximum value of 1A is output for current. The dc switching utilizes 12mA when it is in a dormant state.
