8-string WLED driver provides flexible, accurate dimming control for even LED brightness

Maxim Integrated Products introduces the MAX17061 8-string white-LED (WLED) driver with an integrated MOSFET switch. This device utilizes an internal switch, current-mode, step-up controller to drive the LED array, which can be configured for up to eight parallel strings with ten LEDs per string. To ensure even LED brightness, each string employs a current source that achieves ±1.5% current-balance accuracy between strings. Additionally, the MAX17061 generates a DPWM signal for accurate WLED dimming control. The DPWM's signal is controlled through a PWM interface, an SMBus™-compatible interface, or both.
