A8580 Datasheet - Allegro

A8580 Asynchronous Buck Regulator

Designed to provide the power supply requirements of next generation car audio and infotainment systems, the A8580 provides all the control and protection circuitry to produce a high current regulator with ±1.0% output voltage accuracy. The A8580 employs pulse frequency modulation (PFM) to draw less.

A8580 Features

* Automotive AEC-Q100 qualified

* Withstands surge voltages up to 40 V

* Operates as low as 3.4 VIN (typ) with VIN decreasing

* Utilizes pulse frequency modulation (PFM) to draw only tens of microamperes from VIN while maintaining keep-alive VOUT

* PWM/PFMn mo
