A4408 - Adjustable Frequency Buck or Buck-Boost Pre-Regulator

The A4408 is 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 pre-regulator supplies a 5 V / 115 mAMAX tracking/pro.
