Product Introduction

Overview

The L6563HTR, produced by STMicroelectronics, is a current-mode Power Factor Correction (PFC) controller operating in transition mode (TM). It incorporates the same features as the L6563S with the additional benefit of a high voltage start-up source. This IC is particularly suited for applications requiring compliance with energy-saving regulations and where the PFC pre-regulator acts as the master stage. The device features a highly linear multiplier and a special correction circuit to reduce crossover distortion of the mains current, enabling wide-range mains operation with extremely low Total Harmonic Distortion (THD) even over a large load range.

Q & A

  1. What is the primary function of the L6563HTR?

    The L6563HTR is a current-mode Power Factor Correction (PFC) controller operating in transition mode (TM).

  2. What is the voltage range of the high voltage start-up source?

    The high voltage start-up source operates within a voltage range of -0.3 to 700 V.

  3. What is the purpose of the tracking boost function?

    The tracking boost function allows the output voltage to change in accordance with the mains voltage.

  4. How does the device protect against feedback loop failures?

    The device includes protection against feedback loop disconnection, which triggers a latched shutdown in case of failure.

  5. What is the accuracy of the internal reference voltage?

    The internal reference voltage has an accuracy of 1% at TJ = 25 °C.

  6. What are the key applications of the L6563HTR?

    The L6563HTR is used in PFC pre-regulators for high-end AC-DC adapters/chargers, SMPS compliant with IEC61000-3-2 or JEITA-MITI standards, and SMPS for LED luminaires.

  7. How does the device handle inductor saturation?

    The device includes inductor saturation protection, which temporarily stops the converter and limits the stress on power components in case of inductor saturation.

  8. What is the maximum thermal resistance of the device?

    The maximum thermal resistance, junction to ambient (RthJA), is 120 °C/W.

  9. What is the operating bias current of the device?

    The operating bias current is ≤ 6 mA.

  10. How does the device support remote ON/OFF control?

    The device includes remote ON/OFF control functionality.
