ALLEGRO MICROSYSTEMS A8580 buck regulator boosts flexibility in input voltage (4 to 40V), switching frequency (250kHz to 2.4MHz) and output current (up to 2.5A). Devcies provides the control and protection circuitry to produce a high current regulator with ±1.0% output voltage accuracy. Device employs pulse frequency modulation (PFM) for very low input current while supplying a ‘keep-alive’ voltage supply.
