Description
The Texas Instruments TL3842DR is a pulse width modulation (PWM) controller designed for use in switch-mode power supplies. This IC has a wide input voltage range of 7V to 60V and can handle a maximum switching frequency of 500kHz. A key feature of this device is the internal soft start circuit, which prevents abrupt turn-on of the switch and reduces the stress on the power components. The TL3842DR has a precision reference voltage of 5V with a 1% accuracy, which makes it easy to design a reliable power supply with stable output voltage. Additionally, this IC has a shutdown pin that allows the user to turn off the output and reduce power consumption when the power supply is not in use.
The Texas Instruments TL3842DR has various protection features including cycle-by-cycle current limiting, overvoltage protection, and thermal shutdown. Furthermore, the TL3842DR has a current sense input that enables the user to monitor the output current and facilitate overload protection. The TL3842DR is available in an 8-pin SOIC (small outline integrated circuit) package, which is a space-saving form factor suitable for use in a wide range of power supply applications. Overall, the Texas Instruments TL3842DR is a highly integrated, reliable, and cost-effective PWM controller solution for power engineers
