FSL206MRL is a monolithic integrated circuit specifically designed to meet the requirements of high frequency, off-line switching converters and AC-DC adapters. Its low cost and wide range of applications make it ideal for applications such as LED lighting, adapter control and emergency lighting. The FSL206MRL integrates high speed and low power with excellent reliability and wide range of applications, making it one of the most useful Integrated Circuits for off-line switching converters.

The FSL206MRL is an active current mode PFC controller forflybacktopologies, designed for fixed frequency, constant-current/constant ontime (CRM/COT) control of switching power supplies. It offers a high precision current feedback loop circuit which provides a high level of stability, greatly reducing theover-currentfor safety, reliability and superior performance.TheFSL206MRL has an integrated over-current protection, 400V start-up clamp, standby mode, over-voltage protection and integrated active reset function. In such application, the controls circuit continuously monitors the current supplied to the electrical load and adjusts the output voltage to the desired level automatically.

The FSL206MRL supports high frequency operation in a range of 5 to 500 kHz, making it suitable for very compact power supplies.The power supply stage is based on a low cost MOSFETtrans-conductance amplifier, making it energy efficient and cost effective. The FSL206MRL has flexible system control with current and voltage limits and protectionagainstovervoltage, over-current and short-circuit. The current limit, under-voltage lockouts, as well as over-voltage and short-circuit protection devices are integrated onto the same IC.

The FSL206MRL is also capable of detecting and limiting the output so that the efficiency of the system is maximized, while providing good transient response to load changes. The load switching is precisely timed to regulate the output voltage accurately. The ramp-up and ramp-down of voltage and current is controlled by a timing capacitor and an internal oscillator. The oscillator is programmed by the resistors connected to the pins 2 and 5. By adjusting these resistors, the oscillator can be set for optimum efficiency and faster response. The output voltage and current can also be monitored using the pins 3 and 4.
