TLD6099-2ES Multitopology DC-DC controller suitable for adaptive driving beam (ADB)

Overview

The TLD6099-2ES is a dual channel multi-topology DC-DC controller for LED applications with built-in protection features for a compact LED driver. Each channel drives an external NMOS to discharge the output capacitance fast, managing load variations. Typical user cases are switching from low beam to high beam or driving adaptive driving beam with matrix manager.
