Product Description
STMicroelectronics L6563HTR is a specialized Power Factor Controller IC designed for advanced power management applications. Operating at a switching frequency of 70 kHz, this device supports a 16-pin SO surface mount package and functions within a supply voltage range from 10.3 V to 22.5 V.
The IC features an onboard 700 V start-up source and a low start-up supply current of 150 μA, enabling efficient startup sequences with minimal power loss. It provides a maximum source current of 4 mA and maximum sink current of 4.5 mA, ensuring effective drive capability for external components.
Integral functions include a fast bidirectional input voltage feedforward with 1/V2 correction, tracking boost function, and an accurate adjustable output overvoltage protection. The device incorporates protection against feedback loop disconnection via latched shutdown and an inductor saturation protection mechanism, ensuring long operational reliability.
The totem pole gate driver delivers high current drive strength of -600 mA to +800 mA with active pull-down during under-voltage lockout (UVLO), enabling robust switching performance. Remote ON/OFF control capability and an interface for cascaded converter PWM controllers provide versatility in complex power conversion systems.
This IC operates reliably over an extended temperature range from -40°C to 150°C, suitable for demanding industrial, commercial, and LED lighting applications. Typical usage includes PFC pre-regulators for high-end AC-DC adapters and SMPS for LED luminaires, contributing to efficient energy conversion and power quality improvement.
