LED driver maximizes performance, reduces board space

LED driver maximizes performance, reduces board space

Designed for driving high-power LEDs, the BCR 450 LED driver IC, in combination with an external transistor, features highly precise current control and thermal protection, as well as overvoltage and overcurrent protection functions. The application circuit with the chip has a low component count and is free of inductors, capacitors, and a free-wheeling diode, resulting in a very small PCB space requirement and extending the lifetime of the LED system.

By simply changing the external transistor, manufacturers of LED lighting have the flexibility to adapt output currents from 100 mA to above 1 A. In addition, with its output current precision varying only ±10% over the entire operating temperature range, the BCR 450 strongly supports the homogenous light output requirement for LED lighting fixtures. It is housed in a 6-pin SC74 package. (Less than $0.35 ea/50,000 — available now.)
