UC1844AMDREP Overview


Capsuled in the 8-SOIC (0.154, 3.90mm Width) package, the switching controller can be used for a wide range of applications. There is enough capacity in the dc motor controller to generate the output for the 1 input. Tape & Reel (TR) solid enclosure protects the pmic. With this function, you can deal with Transistor Driver dc switching's outputs (s). dc controls with 10V~30V voltage are supplied and operated. Workable in an dc switcher where -55°C~125°C TA is the -55°C~125°C TArm. This switching controller can switch at Up to 500kHz. The Surface Mount allows it to be used for dc dc regulator in general. Switching control is made easier with the dcdc regulator's Frequency Control. 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 8 terminations. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. DC switcher's voltage input is 15V. Search for "UC1844" to find other relevant dc to dc converter ics. Pins number 8 of switching converter in total. Specially, switching converter corresponds to type Switching Regulator or Controllers. As determined by the test statistics, the output voltage of DC regulator is 13.5V. You should note that the dc dc regulator's usual output current is 200mA. As a result of this, the maximum duty cycle of the voltage regulator dc to dc must remain 50 % during power-up and power-down. Switching controllers work at 500kHz Hz. The dc switching utilizes 11mA when it is in a dormant state. The maximum input voltage of dc switcher is 25V, so users should limit their voltage accordingly. Output current will not exceed 200mA. Its datasheet indicates the switching converter can output a maximum of 15V volts. An input of 11mA current flow could satisfy the operation of the switching converter .
