Allegro MicroSystems A8600
the A8600 provides all the control and protection circuitry to produce four high current regulators, each with ±1.5% accuracy. The A8600 includes control circuitry to implement three adjustable, asynchronous buck regulators with integrated MOSFETs. The always-on regulator operates down to at least VIN of 3.6 V (VIN falling).| Part No. | A8600 |
