It is an improvement over the ACT4529 with its QC2.0 compatibility in 12 V automotive applications. The ACT4530M eliminates the issue with QC2.0 buck converters that try to operate with VIN = 12 V to Vout = 12 V. In addition to QC2.0, it also supports Apple, Samsung and BC1.2 protocols. ACT4530M also has an optional input pin, PDC, that accepts a tri-sta...
