The MAX25510/MAX25511 are 4-channel, white-LED backlight drivers with an integrated current-mode boost converter that operate over a switching frequency range of 400kHz to 2.2MHz and incorporate spread spectrum. Phase-shifting of the output channels is included as an option to further reduce EMI.
The devices provide up to 120mA per channel and include a control output for an external nMOS series switch. These devices are capable of operating down to 3V after start-up.
The MAX25510 has a boost current limit of 3A (min), while the MAX25511 implements a higher minimum current limit of 4.5A for increased output power.
The MAX25510/MAX25511 are available in a compact TQFN package and operate over the temperature range -40°C to +125°C.
Applications
- Automotive Central Information Displays
- Automotive Head-Up Displays
- Automotive Instrument Clusters
