MAX8790AETP+TG51 Description

Short technical summary and product information.

The MAX8790AETP+TG51 from Analog Devices is a high-efficiency driver specifically designed for white light-emitting diodes (LEDs) used in large liquid crystal displays (LCDs). It functions as a current-mode step-up controller, capable of driving up to six parallel strings of series-connected LEDs.

This driver ensures uniform brightness with ±1.5% current regulation accuracy between strings. It supports a wide input voltage range from 4.5V to 26V and provides a full-scale LED current that is adjustable from 15mA to 27mA, or a fixed 20mA. The device offers a broad 100:1 dimming range through two control modes: direct DPWM mode and analog dimming mode, which allows LED current control down to 1%.

Protection features include separate feedback loops for open/short LED detection, cycle-by-cycle current limit, soft-start capability, and thermal shutdown. The MAX8790AETP+TG51 utilizes an external MOSFET for scalable output power and maximum operating voltage. It operates with selectable switching frequencies of 500kHz, 750kHz, or 1MHz, allowing for trade-offs between component size and efficiency. The device is housed in a thermally enhanced, 20-pin, 4mm x 4mm thin QFN package.
