TLD5099EP

Active and preferred

The TLD5099EP features an integrated pulse width modulator for easy dimming function implementation with reduced color shifting and a spread spectrum modulator for improved EMI performance. It supports fixed current and fixed voltage configurations in Boost, Buck, Buck-Boost, SEPIC, and Flyback topologies by adjusting external components. Additionally, it drives a low side n-channel power MOSFET from an internal 5V linear regulator.
