The MAX16814BEUP+ is an automotive-grade, 4-channel high-brightness LED driver controller from Analog Devices. It integrates a current-mode switching DC-DC controller that supports boost, buck, SEPIC, and coupled-inductor boost-buck topologies. The device operates from an input voltage range of 4.75V to 40V, making it suitable for automotive load-dump conditions. Each channel can be programmed to deliver LED current from 20mA to 150mA using an external resistor, with ±3% accuracy.
The driver offers PWM dimming with a minimum pulse width as low as 1µs and a dimming ratio of 5000:1 at 200Hz. The switching frequency is programmable from 200kHz to 2MHz, allowing optimization between efficiency and component size. The device includes a shutdown current of less than 40µA.
The MAX16814BEUP+ is designed for automotive lighting applications such as backlighting and general lighting. It is available in a 20-pin TSSOP package with an exposed pad (20-TSSOP-EP), surface-mount mounting. The operating temperature range is -40°C to +125°C, meeting automotive requirements.
