High Efciency Integrated Boost Driver For 3-Strings Of 30mA LEDs

The SC443 is a high-efficiency multiple string WLED driver with an integrated boost converter. It operates over a wide input range from 4.5V to 27V with a maximum output voltage of 42V and a 1A internal power Switch It CAN drive 3 strings with current up to 30mA per string. The string-to-string current matching is within, typically, 1% and the overall efficiency is greater than 90% due to the low Current Sense voltage and a low-impedance internal power Switch The wide PWM dimming range boasts a ratio of 250: 1.
