UC2827DW-2G4 Overview


This switching controller fits most application requirements since it is packaged in a SOIC package. For 3 outputs, the dc motor controller is appropriate. The switching controller can be switched at 500kHz. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. The switching converters's terminals (s) are designed at DUAL. Various 24 terminations. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. It is inputted with a DC switcher's voltage of 15V. There are 24 pins on switching converter. Switching converter type is specifically Switching Regulator or Controllers. To ensure the reliability under power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set as 95 %. 450kHz is the frequency of the switching controller. Hence, CAN ALSO WORK IN CURRENT MODE is used to better suit the DC to DC voltage regulator's situation. Ideally, dc regulator should be kept at a temperature of -40°C or higher. At a temperature around 85°C degrees Celsius, dc regulator should be running. Overall, the switch converters contains 1 function(s). A voltage regulators switching with 24 pins is designed. There is a maximum frequency of 500kHz that can be switched by the controller. For nominal working status, the input voltage can be set as 15V. With 100mA inputs, switching controller is ideal. In normal operation, it outputs 2.5V. The supply voltage must be 15V. Maximum supply voltage is 20V.
