Analog Devices / Maxim Integrated MAX25510 & MAX25511 Integrated Boost Converters

Analog Devices MAX25510 and MAX25511 Integrated Boost Converters are 4-channel, white-LED backlight drivers. These Analog Devices converters have an integrated current-mode boost converter that operates over a switching frequency range of 400kHz to 2.2MHz and incorporates a spread spectrum. Phase-shifting of the output channels is included as an option to further reduce EMI.
