• Typical Application for A8590 Wide Input Voltage, 2.4 MHz, 3.0 A Asynchronous Buck Regulator With Low-IQ Standby, Sleep Mode, External Synchronization, and NPOR Output. Designed to provide the power supply requirements of next generation 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 uA from 12 VIN while supplying 3.3 V/40 uA. After startup, the A8590 operates down to at least 3.6 VIN (VIN falling)
