The FT8870 LED Driver Family is Announced by Fremont Micro Devices

The FT8870 is a High Performance Non-Isolated Buck LED Driver for DC/DC or AC/DC LED Lighting Applications. The Integrated 500V Power MOSFET Enables Constant Current Control Designs without a Secondary Sense and Feedback Circuit.

FREMONT, CA, September 15, 2014 /24-7PressRelease/ — Fremont Micro Devices USA Inc announced the FT8870 Family of primary side drivers for LED applications. The first four members of the Family include the FT8870S (7W), FT8870A (10W), FT8870C (15W) and FT8870CD (22W). These high precision devices simplify LED lighting system design by eliminating the secondary side feedback components plus opto-coupler and are optimized for low cost non isolated Buck switching mode LED applications like back lighting of flat panel display applications.

The FT8870 integrates a 500V Power MOSFET that improves system reliability and lowers cost and complexity of the design.

“The FT8870 Family adds to the growing portfolio of Fremont Micro Devices LED solutions. The FT8870 Family operates in the induction current boundary conduction mode with demagnetization sensing technology. The low operating current does not require auxiliary winding for output current sensing and chip power supply.” said, Jim Panfil, Vice President of Sales and Marketing at Fremont Micro Devices USA. “The highly integrated functions like leading edge banking and built in line compensation offer a high efficiency low cost solution for constant current LED driver applications.” He added.

These devices have a sophisticated current sensing method with an LED current accuracy of 3%. The built in protection functions including LED open / short circuit protection, over temperature compensation, CS resistor short circuit protection and VCC under voltage lockout, which greatly enhance system reliability and safety.
