The MAX17061AETI+ from Analog Devices is a high-efficiency driver for white light-emitting diodes (LEDs), specifically designed for large liquid-crystal displays (LCDs). It utilizes an internal switch current-mode step-up controller to drive LED arrays, configurable for up to eight strings in parallel with 10 LEDs per string. This configuration ensures even LED brightness with ±1.5% current-regulation accuracy between strings.
The device operates over a wide input voltage range from 4.5V to 26V and provides a full-scale LED current adjustable from 15mA to 30mA, or a fixed 25mA. Accurate WLED dimming control is achieved through an internally generated DPWM signal, with an 8-bit resolution, controllable via SMBus or an external PWM signal. The selectable switching frequency (500kHz, 750kHz, or 1MHz) allows for trade-offs between component size and operating frequency.
Multiple protection features are integrated, including separate feedback loops for output voltage limiting, open and short LED detection, cycle-by-cycle current limit, soft-start capability, and thermal shutdown. The MAX17061AETI+ is available in a thermally enhanced 28-pin, 4mm x 4mm Thin QFN package, suitable for surface mounting.
Key electrical specifications include a wide input voltage range, adjustable output current, selectable switching frequencies, and 8-bit dimming resolution. The device is designed for backlight applications, offering robust protection mechanisms for reliable operation.
