3A Buck Regulator Features Enhanced Idle/Stop/Start Recovery

3A Buck Regulator Features Enhanced Idle/Stop/Start Recovery
Allegro MicroSystems Inc.

Providing power for next generation car audio and infotainment systems, the A8590 buck regulator packs all the control and protection circuitry necessary to produce a 3A regulated output. Capable of withstanding the rigors of wide automotive battery input voltages, the A8590 can also be used in cluster and center stack applications as well as in advanced driving assistance systems. It employs pulse frequency modulation (PFM) to draw less than 50 μA from 12 VIN while supplying 3.3V at 40 μA. After startup, the A8590 operates down to at least 3.6 VIN (VIN falling) and maintains ±1% output voltage accuracy. Other features include PWM/mode control, the ability to synchronize PWM frequency to an external clock, and a pin for an ultra-low current shutdown mode. Available in a 16-pin TSSOP with exposed power pad (suffix LP), pricing is $1.75 each/1,000.
