TPS92411EVM-001에 대한 설명
The TPS92411EVM-001 implements a 120VAC, 12W, phase dimmable light engine with high power factor and low LED current ripple on a single-sided metal core printed circuit board (MCPCB). The included LED drive circuit is comprised of a high voltage linear regulator and TPS92411 floating switches arranged to toggle three segments of a high-voltage LED string at eight discrete points during an AC half-cycle. Unlike traditional switched mode power supply (SMPS) converters, the TPS92411EVM-001 uses no magnetic components or high speed switching for power processing.
