General Description
The MAX25561 is a 6-channel LED backlight driver with an integrated current-mode boost controller that operates over a switching frequency range of 400kHz to 2.2MHz and incorporates spread spectrum. Selectable phase-shifting of the output channels is included to reduce EMI. The MAX25561 provides up to 220mA per channel. The device is capable of operating down to very low battery voltages by virtue of a unique input voltage switching scheme.
Extensive diagnostics and an I2C interface are included to assist with system ASIL B compliance.
The MAX25561 is available in a compact TQFN package and operates over the -40°C to +125°C temperature range.
