Infineon MOSFET Gate Driver for BCR601, BCR602 for Motors

The Infineon REF_TW_BCR601_55V_0.5A tuneable 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.

Linear regulators give considerable cost advantage over buck topology
Cost advantage increases with additional channels
Efficiency can be on par with the buck (depends on output ripple of the first stage)
Highest light quality, zero ripple
Deep, full analogue dimming
