UC1845AMDREPG4 Overview
With its 8-SOIC (0.154, 3.90mm Width) package, the switching controller fits the needs of most applications. For 1 outputs, the dc motor controller is appropriate. Packaging for the pmic consists of Tape & Reel (TR) solid enclosures. The system can process Transistor Driver dc switching's outputs (s). The supply and operating voltage of the dc control are 7.6V~30V. Workable in an dc switcher where -55°C~125°C TA is the -55°C~125°C TArm. A switching controller such as this can switch at a value of Up to 500kHz . The Surface Mount makes it ideal for general dc dc regulator. To provide efficient switching control, Frequency Control is included in the dcdc regulator. SWITCHING CONTROLLER analog IC connects the switch converters. The switching converters's terminals (s) are designed at DUAL. 8 terminations with various dc switching's functions. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. DC switcher's voltage input of 15V. Other relevant dc to dc converter ics can be found by searching "UC1845". In total, switching converter has 8 pins. Switching converter type is specifically Switching Regulator or Controllers. Voltages 25V are the maximum that the dc to dc regulator will accept. 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 50 %. DC regulator has a maximum frequency of 500kHz.
