Description
General part information
MAX25512B Series
The MAX25512B is a 4-channel white LED backlight driver with an integrated current-mode boost converter that operates over a switching frequency range of 400kHz to 2.2MHz and incorporates spread spectrum. Phase-shifting of the output channels is included as an option to further reduce electromagnetic interference (EMI).The device provides up to 120mA per channel and includes a control output for an external nMOS series switch. It is capable of operating down to 3V after startup. The device is hybrid-dimming-capable and provides a brightness calibration feature through a dedicated DAC. It can benefit from these two functions simultaneously.The MAX25512B has an I2C interface to enable flexibility of control and detailed diagnostics. The MAX25512B is available in a compact TQFN package and operates over the -40°C to +125°C temperature range.APPLICATIONSAutomotive Instrument ClustersAutomotive Central Information DisplaysAutomotive Head-Up Displays
