REFTWBCR60155V05ATOBO1

REF_TW_BCR601_55V_0.5A tunable white reference design with 2 channels uses BCR601 and BCR602 linear regulators to provide a very stable LED current which is completely free of any ripple or temporary fluctuations. Consequently, the light output is completely free of any artefacts like flicker or stroboscopic effects. Thanks to the active headroom control (AHC) of BCR601, the output of the primary stage of the board, which is attached to, is regulated to maximize efficiency to levels that are quite similar to switched-mode regulators. The cost-effectiveness especially in multichannel designs can be further enhanced by using BCR602 in a tiny SOT23-6 package regulating the LED current for flicker-free deep dimming performance.

• BCR601 as controller controls voltage overhead of both channels and current of one channel
• BCR602 as controller regulates the current of the second channel
• Input voltage up to 60V
• Can be operated with either BJT or N-channel MOSFET
• Analogue dimming down to 3%, PWM dimming down to 1% (BCR602)
• Current precision ±3%
• OTP, OVP, hot-plug protection
