The MAX17061ETI+T from Analog Devices is a high-efficiency driver for white light-emitting diodes (LEDs), specifically designed for large liquid-crystal displays (LCDs). It features a current-mode step-up controller capable of driving up to eight parallel strings, with 10 LEDs per string.
This LED driver operates within a wide input voltage range of 4.5V to 26V. It provides a full-scale LED current that is adjustable from 15mA to 30mA, or a fixed 25mA. The device supports accurate WLED dimming control through an internal DPWM signal, programmable via resistor or controlled through an SMBus™ interface. The dimming range offers 8-bit resolution.
Key electrical specifications include selectable switching frequencies of 500kHz, 750kHz, or 1MHz, allowing for a trade-off between component size and operating frequency. The device integrates a 150mΩ (typ) power MOSFET with a 45V maximum rating. It also includes features for accurate current regulation between strings (±1.5%) and a low feedback voltage of 625mV (typ) at 25mA LED current.
The MAX17061ETI+T is housed in a thermally enhanced 28-pin, 4mm x 4mm Thin QFN package, suitable for surface mounting. It includes protection features such as open and short LED detection, output overvoltage protection, cycle-by-cycle current limit, and thermal shutdown.
