Analog Devices Inc. MAX25561 ASIL B LED Backlight Drivers are 6-channel devices with an integrated current-mode boost controller that operates over a switching frequency range of 400kHz to 2.2MHz and incorporates a spread spectrum. Selectable phase-shifting of the output channels is included to reduce EMI. The TQFN packaged MAX25561 provides up to 220mA per channel and operates within a -40°C to +125°C temperature range. The Analog Devices MAX25561 can operate down to very low battery voltages by a unique input voltage switching scheme. Extensive diagnostics and an I2C interface are included to assist with system ASIL B compliance.
