The LNK613DG-TL is an integrated, offline two-switch forward converter PWM controller with a 700mA power switch. This device provides improved system efficiency by utilizing pulse width modulation (PWM) to regulate the output voltage. The current sense voltage is used to adjust the switching frequency to achieve excellent dynamic control of the output voltage and current. The device also integrates a number of functions and protections to increase system robustness such as short circuit protection, over current protection, thermal shut down and over voltage protection, making it a good choice for a wide range of applications.

The LNK613DG-TL application field includes AC/DC converters, offline switchers, LED lighting power supplies and general power converters. It features a wide input supply range of 8V to 38V and an output voltage range of 5V to 24V. The device offers excellent power conversion efficiency of up to 92% and a low standby power consumption of 4mW.

The LNK613DG-TL working principle starts when the device is switched on by an input signal. It then takes the input voltage and converts it into a current, which is then regulated by the PWM controller to drive the MOSFETs. The PWM controller senses the output voltage via a sense resistor to provide a closed loop feedback and ensures that the output voltage remains stable. The device then adjusts the switching frequency to achieve a better control of the output voltage and current. Additionally, the LNK613DG-TL provides a number of protections such as short circuit protection, over current protection, thermal shut down and over voltage protection.

In conclusion, the LNK613DG-TL is an integrated, offline two-switch forward converter PWM controller with a 700mA power switch. It features a wide input supply range of 8V to 38V and an output voltage range of 5V to 24V, making it well-suited for applications in AC/DC converters, offline switchers, LED lighting power supplies, and general power converters. The device also provides a number of functions and protections to ensure robustness and excellent dynamic control of output voltage and current.
