MAX16818 1.5MHz, 30A High-Efficiency LED Driver With Rapid LED Current Pulsing

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 T 4db he MAX16818 is the first LED Driver controller that enables Maxim's patent-pending technology for fast LED current transients of up to 20A/s and 30kHz dimming frequency.
This device utilizes average-current-mode control that enables optimal use of MOSFETs with optimal charge and on-resistance characteristics. This results in the minimized need for external heatsinking even when delivering up to 30A of LED current. True differential sensing enables accurate control of the LED current. A wide dimming range is easily implemented to accommodate an external PWM signal. An internal Regulator enables operation over a wide input voltage range: 4.75V to 5.5V or 7V to 28V and above with a simple external biasing device. The wide switching frequency range, up to 1.5MHz, allows for the use of small inductors and capacitors.
The MAX16818 features a Clock output with 180 phase delay to control a second out-of-phase LED Driver to reduce input and output Filter capacitors size or to minimize ripple currents. The MAX16818 offers programmable hiccup, overvoltage, and overtemperature protection. The MAX16818ETE+ is rated for the extended temperature range (-40C to +85C) and the MAX16818ATE+ is rated 4f9 for the automotive temperature range (-40C to +125C). This LED Driver controller is available in a lead-free, 0.8mm high, 5mm x 5mm 28-pin TQFN package with exposed paddle.
