The A8590 is an automotive-grade asynchronous buck regulator designed for automotive infotainment and audio systems, delivering up to 3.0 A output current with a 2.4 MHz switching frequency. It operates from an input voltage as low as 3.4 V and withstands surge voltages up to 40 V. The device features pulse frequency modulation (PFM) for low standby current under 50 µA at 12 V input, a SLEEP mode consuming less than 5 µA internal current, and an active-low NPOR output. It is AEC-Q100 qualified, operates with an ambient temperature range of -40°C to 125°C, and is packaged in a 16-pin TSSOP with an exposed thermal pad. Output voltage accuracy is ±1.0% from 0°C to 85°C and ±1.5% from -40°C to 150°C.
The A8590 offers robust and efficient power conversion for automotive applications, featuring low-Iq standby operation, a sleep mode, external synchronization, and enhanced idle/stop recovery for improved transient performance.
