NCL30100ADLMGEVB: Compact Switching Buck LED Driver Evaluation Board
The NCL30100 is a compact switching buck LED driver controller intended for space constrained constant current high brightness LED driver applications where high efficiency and small size are important. This demo board illustrates the NCL30100 in a form factor suitable to be embedded in the base of an MR16 LED light bulb. In this case the dual sided PCB incorporates a low voltage AC rectifier bridge so that it can accept the 12 Vac input commonly used in MR16 applications. The controller is based on a peak current, quasi fixed off-time control architecture optimized for continuous conduction mode stepdown (buck) operation. This allows the output filter capacitor to be eliminated. In this configuration, a reverse buck topology is used to control a cost effective N-channel MOSFET. The Demo board has multiple FET footprints to allow for optimal FET selection. The footprints include SOT23, SOT363, SOT223 and as built, a TSOP6.
