SC441A - High Efficiency Integrated Driver

Description

The SC441A is a high-efficiency multiple string WLED driver with an integrated boost converter.

It operates over a wide input range from 4.5V to 21V with a maximum output voltage of 36V and a 2.5A internal power switch.

It can drive up to forty WLEDs in 4 strings with current up to 150mA per string.

Features

  • High Efficiency Integrated Driver for 4-Strings of 150mA LEDs.

SC441A www.DataSheet4U.com POWER MANAGEMENT Features                High Efficiency Integrated Driver for 4-Strings of 150mA LEDs Description The SC441A is a high-efficiency multiple string WLED driver with an integrated boost converter. It operates over a wide input range from 4.5V to 21V with a maximum output voltage of 36V and a 2.5A internal power switch. It can drive up to forty WLEDs in 4 strings with current up to 150mA per string. The string-to-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 boasts a ratio of 500: 1.
