High Efficiency Integrated Driver for 4-Strings of 150mA LEDs Description The SC445 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 and can sustain fast Vin transient up to 5V/µs. It can drive up to forty WLEDs in 4 strings with current up to 150mA per string. The stringto-string current matching is 2% typical, 3% maximum. 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 ... |
