Fremont Micro Devices Announces a New LED Driver Design Kit

Fremont, California (EastBayDaily) — Fremont Micro Devices USA Inc. announced a new design kit for the FT838R that reduces the design time of AC/DC LED driver applications. The FT838R has a direct drive to a bipolar junction transistor (NPN) or MOS switch. The low operating current reduces the Vcc hold up capacitance requirement. The extremely low start-up and operating current reduces power consumption which improves system reliability.

The reference design targets LED lighting products. “The design kit includes a functional evaluation board plus the schematic and bill of materials for 6 -10W LED driver design.” said Shu Min Panfil, Director of Corporate Communications, for Fremont Micro Devices USA. “These tools accelerate time to market because the evaluation board is fully functional and debugged. The schematic includes a wiring circuit diagram and electrical specifications,” she added.

The LED current can be accurately regulated by sensing the primary side information with a few external components without the need for an opto-coupler and TL431. The integrated under Voltage Lockout and Leading Edge Banking provides the user a high efficiency and low cost solution for LED lighting products.

The FT838R in a SOT23-5 package has a list price of $0.08 for volume orders of 10ku. The design kit is available from stock.
