UC3842BN Product Details

UC3842BN Overview


As a result of 8-DIP (0.300, 7.62mm) compact design, the switching controller is compatible with most applications. There is sufficient capacity to generate switching controller for outputs 1. The pmic is packaged in Tube solid enclosure. Transistor Driver dc switching's outputs (s) are supported. 10V~30V is the supply voltage and the operating voltage of the dc control. Workable in an dc switcher where 0°C~70°C TJ is the 0°C~70°C TJrm. A switching controller such as this can switch at a value of Up to 500kHz . It is suitable for general dc dc regulator when it is set to Through Hole. Frequency Control is used for efficient switching control in the dcdc regulator. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. The switching converters's terminal (s) are designed at DUAL . A variety of 8 terminations are available in dc switching. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 15V. UC3842 can be used to locate other relevant dc to dc converter ics. 8 pins are on switching converter. Switching converter is a special type of Switching Regulator or Controllers. Based on the test statistics, DC regulator outputs voltage 5.1V. You should note down the dc dc regulator's usual output current of 200mA 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 100 %. In most applications and prototypes, DC switcher's Through Hole makes it suitable. A frequency of 250kHz is used by the switching controller. DC switchings that are dormant use 12mA. Input voltage can be set to 15V for nominal working status. There is a possibility of damage to the component if the switching voltage regulators current exceeds 17mA.
