General Description
The MAX16818 pulse-width modulation (PWM) LED driver controller provides high-output-current capability in a compact package with a minimum number of external components. The MAX16818 is suitable for use in synchronous and nonsynchronous step-down (buck) topologies, as well as in boost, buck-boost, SEPIC, and Cuk LED drivers. The MAX16818 is the first LED driver controller that enables Maxim’s technology for fast LED current transients of up to 20A/µs and 30kHz dimming frequency.
