Image of Infineon Technologies' Low Cost Linear Discrete LED Drivers Infineon Technologies' linear-mode LED driver family, BCR401, BCR402, and BCR405, and newly introduced BCR450 provide efficient, low-cost constant-current solutions for LED strings from 10 mA to 65 mA (up to 700 mA with an external "boost" transistor). Our constant-current drivers keep light emission consistent over power supply and temperature variations, eliminate the effect of V_F variation, and help prevent thermal runaway in applications. We also offer low forward-voltage Schottky diodes, including single-package reverse polarity protection diode arrays (RPP).

Features

Constant current adjustable from 10 mA to 60 mA, up to 500 mW power dissipation
Current range may be extended up to 700 mA with addition of external "boost" transistor (for example BCX68-16)
Selection of 18 V or 40 V maximum rating across driver
ON / OFF feature enables PWM / FM modulation
LED-circuit protection due to negative-temperature coefficient (NTC)

Applications

Channel lighting
Advertising signage
Home/office lighting (recess lamps, pendant lamps, and more)
Rope lighting / neon replacement
Automotive (for example center high-mounted stop light "CHMSL")

Benefits

Enables using more LEDs in one branch due to low-voltage drop compared to resistor biasing schemes
Maintains consistent light emission across LED strings independent of V_F, power supply, and temperature variation

Efficient active current regulation, accuracy of IOUT at ±1%/V voltage variation
Eliminates problem of stocking multiple bias resistor values to match incoming LED V_F bins
