Qorvo MAX25660 Automotive Low-Noise Synchronous Buck-Boost Converter

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.
