Description
General part information
MAX25660 Series
The MAX25660 is a small, synchronous, buck-boost converter with integrated H-bridge switches. This IC provides a fixed-output regulation voltage and an externally adjustable output voltage in the 2.75V to 10V range with an input voltage above, below, or equal to the output regulation voltage. The MAX25660AFFA has a 9A (typ) input current limit, while the MAX25660AFFB has a 10.8A (typ) input current limit. Both versions can support continuous load currents up to 6A, which depends on the input-to-output voltage ratio and operating frequency. It also has a wide input voltage range of 3.6V to 36V. The MAX25660 features automatic loop bandwidth adjustment that automatically changes the loop bandwidth, which depends on the operating mode. This allows for a very fast transient response time when in Buck mode, which reduces audible noise caused by large changes in the load.The MAX25660 has two switching frequency options: 2.1MHz and 400kHz. The 2.1MHz high switching frequency allows for small external components and reduced output ripple, and guarantees no AM band interference, while the 400kHz switching frequency offers better efficiency and relieves the power consumption concern. The IC also includes spreadspectrum frequency modulation to minimize EMI interference.The MAX25660 features a power-good (PGOOD) indicator, undervoltage lockout, overvoltage protection, cycle-by-cycle current limit, and thermal shutdown. The ICs are available in a small, 4.25mm x 4.25mm x 0.75mm, 22-pin FC2QFN package.APPLICATIONSDisplay ApplicationsTail-Light and Front-Light ApplicationsPoint-of-Load Power Supplies
