It also includes an integrated pulse width modulator to easily implement a dimming function with reduced color shifting and a spread spectrum modulator to improve the EMI performance. It is designed to support fixed current and fixed voltage configurations in multiple topologies such as Boost, Buck, Buck-Boost, SEPIC and Flyback by simply adjusting the external components. The TLD5099EP drives a low side n-channel power MOSFET from an internal 5 V linear regulator.
