Semtech SC5010
High Efficiency 8-Channel LED Driver with I2C Interface and Phase-Shifted PWM Dimming
The SC5010 is an 8-channel high-precision, high-efficiency step-up (Boost) LED driver for backlight applications. It features wide input voltage range (4.5V to 27V) , fl exible output configuration, wide analog and PWM dimming range, phase shifting and fading. It also features video signal synchronization (VSYNC), I2C interface, and numerous protection features. An optional disconnect p-MOSFET provides true load disconnection and inrush current limiting.
