Working Principle

The working principle of this voltage regulator is based on the synchronous rectification and PWM control. The device uses an external MOSFET as the main switch and a synchronous rectifier to complete the low side power conversion. It uses an oscillator to control the pulse width of the switch, thus regulating the output current and achieving the output voltage regulation.

When the input voltage is too low or too high, the device will enter into a protection state in order to protect the device. Also there are many adjustable parameters to optimize the regulation, such as over-current, over-voltage and over-temperature protection which trigger the device to shut down for safety.

In summary, the TPS62085RLTT is a synchronous voltage regulator with integrated switching MOSFETs targeted for high power conversion applications and is suitable for consumer and high power LED lighting, power adapter, DC/DC converter and power management. It uses synchronous rectification, PWM control, and many protection functions to ensure the safe operation of the system.
