Infineon Technologies Tunable White LED Driver Reference Design

Infineon Technologies REF_TW_BCR601_55V_0.5A Tunable White LED Driver Reference Design features two channels and uses the BCR601 and BCR602 linear regulators to provide a very stable LED current that is completely free of any ripple or temporary fluctuations. Additionally, the light output is entirely free of any artifacts like flicker or stroboscopic effects.

The Infineon Tunable White LED Driver Reference Design includes the BCR601, which offers active headroom control (AHC) regulated to maximize efficiency to levels that are quite similar to switched-mode regulators. The cost-effectiveness, especially in multichannel designs, is further enhanced by using BCR602 in a tiny SOT23-6 package regulating the LED current for flicker-free deep dimming performance.

Features

BCR601 as the master controller controls the voltage overhead of both channels and current of one channel
BCR602 as slave controller regulates the current of the second channel
Input voltage up to 60V

Can be operated with either BJT or N-channel MOSFET
Analog dimming down to 3%, PWM dimming down to 1% (BCR602)
Current precision ±3%
OTP, OVP, hot-plug protection
