HVLED007TR

Overview

The HVLED007TR is a current-mode Power Factor Correction (PFC) controller designed for isolated high-power-factor flyback converters operating in transition mode. It features an Input Current Shaper (ICS) to achieve low total harmonic distortion (THD). The device supports an input voltage range of 10.5 V to 22.5 V and operates at a frequency of 70 kHz. It provides one output channel with a maximum output current of 800 mA. The adjustable output voltage allows flexibility in design. Operating temperatures range from -40 °C to +125 °C, with a maximum power dissipation of 650 mW.

Feature Summary

• Proprietary Input Current Shaper (ICS) enables high-power-factor quasi-resonant operation with minimal line current distortion.
• Integrated totem-pole gate driver capable of sourcing 600 mA and sinking 800 mA for efficient MOSFET driving.
• Includes comprehensive protection mechanisms such as output overvoltage protection, overload handling, and short-circuit protection.
• Features low start-up and quiescent currents to enhance energy efficiency in lighting applications.

Applications

• Indoor solid-state lighting systems requiring high power factor
• Outdoor solid-state lighting fixtures compliant with EN61000-3-2
• Flyback converter pre-regulators for LED drivers

Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when ordering. Confirm that the SOIC-8 package matches your PCB footprint requirements. Ensure the input voltage range of 10.5 V to 22.5 V aligns with your auxiliary supply design. Check for RoHS compliance documentation if required by your manufacturing standards. Validate that the 70 kHz switching frequency fits your EMI constraints.

Selection Notes

Select this component for designs requiring transition-mode PFC control in flyback topologies. It is suitable for applications needing low THD without complex secondary regulation loops. Consider the 600 mA source and 800 mA sink drive capability for larger MOSFETs. Evaluate the -40 °C to +125 °C temperature range against your environmental conditions. Compare power dissipation limits with your thermal management strategy.

FAQ

What is the function of the Input Current Shaper (ICS)?

The ICS is a proprietary circuit that enables the converter to draw a theoretically sinusoidal input current, achieving low total harmonic distortion (THD) in transition-mode operation.

How does the HVLED007 handle feedback?

It includes a control input designed to be driven by the phototransistor of an optocoupler for secondary-regulated isolated control loops, though it can also support primary-regulated voltage loops with external circuitry.

What protection features are integrated into the device?

The IC includes output overvoltage protection, overload protection, and short-circuit protection to ensure safe operation in lighting environments.
