Description
The A4412 is a power management IC that uses a buck or buck/ boost pre-regulator to efficiently convert automotive battery voltages into a tightly regulated intermediate voltage complete with control, diagnostics and protections. The output of the preregulator supplies a 5 V / 100 mA protected linear regulator, a 3.3 V / 90 mA linear regulator, a 5 V / 200 mA linear regulator, a 5 V / 55 mA linear regulator, a 5 V / 30 mA linear regulator and an adjustable 400 mA synchronous buck r.
