FL7701M

Overview

The FL7701M is a smart, non-isolated PFC buck LED driver IC from onsemi. It features digital active PFC that automatically enables based on AC or DC input detection. The device includes a built-in high-voltage self-bias circuit, eliminating the need for large electrolytic capacitors. Key electrical parameters include a typical operating current of 0.85 mA, an internal reference accuracy of ±3%, and UVLO with 5V hysteresis. It supports programmable oscillation frequency and LED current, along with analog dimming and soft-start capabilities.

Feature Summary

Digital active PFC function automatically enabled by AC input detection
Built-in high-voltage self-bias power supply circuit
Automatic restart over-current protection (AOCP) mode
Integrated thermal shutdown and cycle-by-cycle current limiting

Applications

LED retrofit lamps replacing incandescent, CFL, and linear lights
Decorative and interior lighting applications
Instrument panel illumination systems
Low-power LED lighting fixtures

Procurement Notes

Verify component authenticity through authorized onsemi distribution channels. Confirm package marking matches the SOP-8 specification. Review the latest datasheet revision for any updates to electrical characteristics or recommended operating conditions prior to final design implementation.

Selection Notes

Select this component for non-isolated LED driver designs requiring integrated power factor correction. The digital PFC mechanism simplifies circuit topology by removing external PFC inductors. Ensure the application voltage range aligns with the device's input specifications and thermal management requirements are met for the SOP-8 package.

Part Context

The FL7701M belongs to onsemi's family of smart LED lamp driver ICs. It is designed for direct replacement of traditional lighting ballasts. The device integrates control logic and power stages into a single compact package, targeting cost-sensitive and space-constrained lighting applications.
