HVLED007

Overview

The HVLED007 is a current-mode Power Factor Correction (PFC) controller designed for isolated high power factor flyback converters operating in transition mode. It features a proprietary Input Current Shaper (ICS) to achieve low total harmonic distortion (THD). The device includes an overvoltage protection circuit and supports secondary-regulated isolated control loops via an optocoupler input. It provides overload, short-circuit, and overvoltage protections with auto-restart capabilities. The IC operates within an extended temperature range from -40°C to +125°C and is housed in an SOIC-8 package.

Feature Summary

• Proprietary Input Current Shaper (ICS) enables high power factor quasi-resonant operation with minimal line current distortion
• Integrated control input for secondary-regulated isolated feedback loops using optocouplers
• Comprehensive protection suite including output overvoltage, overload, and short-circuit handling with auto-restart
• Totem-pole gate driver stage capable of sourcing 600 mA and sinking 800 mA for robust MOSFET drive

Applications

• Indoor solid-state lighting applications
• Outdoor solid-state lighting applications
• Switched-mode power supplies (SMPS) up to 100 W compliant with EN61000-3-2 standards

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct packaging and tape-and-reel specifications. Confirm that the selected variant matches the required thermal performance and electrical tolerances for the target application environment. Cross-reference the component marking code with the latest production documentation to avoid counterfeit or obsolete stock issues during procurement.

Selection Notes

Select this controller for flyback topologies requiring transition mode operation to minimize switching losses and electromagnetic interference. Ensure the design accommodates the specific gate drive current requirements for the chosen power MOSFETs. Evaluate the external component values necessary to set the desired output voltage and current limits while maintaining stability across the full input voltage range and load conditions.

Part Context

The HVLED007 belongs to STMicroelectronics' dedicated LED lighting driver family, specifically targeting PFC pre-regulators. It complements other power management solutions by offering a cost-effective approach to achieving regulatory compliance for harmonic currents in medium-power lighting systems. The device integrates advanced control algorithms typically found in higher-cost controllers into a compact surface-mount package.
