A8590 Description
Designed to provide the power supply requirements of nextgeneration car audio and infotainment systems, the A8590 provides all the control and protection circuitry to produce a high-current regulator with ±1.0% output voltage accuracy. The A8590 employs pulse frequency modulation (PFM) to draw less than 50 μA from 12 VIN while supplying 3.3 V / 40 μA. After startup, the A8590 operates down to at least 3.6 VIN (VIN...
