UC3844BDR2G Overview
Capsuled in the 14-SOIC (0.154, 3.90mm Width) package, the switching controller can be used for a wide range of applications. It is sufficient to generate 1 outputs with this dc motor controller. Packaged in solid enclosures, this pmic has a Tape & Reel (TR) rating. Transistor Driver dc switching's outputs (s) are supported. dc controls with 10V~36V voltage are supplied and operated. A 0°C~70°C TA dc switcher is not a problem. This switching controller can switch at Up to 500kHz. As it has a Surface Mount value, it can be used for general dc dc regulator. To ensure efficient switching, this dcdc regulator features a Frequency Control. A SWITCHING CONTROLLER analog IC is connected to the switch converters. Thare switching converters has a terminal (s) at DUAL . The 14 terminations can be used for a wide range of dc switching. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. DC switcher's voltage input of 15V. You can find other relevant dc to dc converter ics by searching "UC384*B". Pins number 14 of switching converter in total. Specially, switching converter corresponds to type Switching Regulator or Controllers. Statistically, DC regulator outputs 5V volts. The dc dc regulator's usual output current is 1A, which should be noted down when you start a project. To ensure the reliability under power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set as 48 %. Having a Surface Mount makes DC switcher ideal for most prototype and application designs. Switching controller operates at 52kHz Hz. A current greater than 17mA may result in improper operation and possibly damage to the component.
