Dual 2-A Synchronous, Low-Voltage Buck Regulator

Allegro MicroSystems, LLC announces a new dual converter for multiple output systems. Allegro’s AEC-Q100 qualified A8651 is a dual 2-A, low VIN, synchronous regulator with an adjustable frequency, integrated highside, P-channel MOSFET and a low-side, N-channel MOSFET. The A8651 incorporates current-mode control to provide simple compensation as well as excellent loop stability. The device utilizes external compensation to accommodate a wide range of power components to optimize for transient response without sacrificing stability.

The A8651 regulates input voltages from 2.5V to 5.5V, down to output voltages as low as 0.8V and is able to supply up to 2A of load current per regulator. This new device includes many robust protection features that are well-suited for automotive requirements.

It was designed specifically for automotive infotainment, GPS, telecom, networking and home/professional entertainment system applications. Allegro's A8651KLPTR-T is available in a 20-lead eTSSOP (LP) package and is priced at $2.13 in quantities of 1,000.
