Overview
A8600 Quadruple Output Regulator with Two High-Side Switches, BU/ACC Voltage Detectors, and Mute Delay FEATURES AND BENEFITS • Four independent, high current switching regulators • Adjustable 1.
0 A/±1.
5% always-on asynchronous buck regulator with an integrated 150 mΩ MOSFET (SW1) ▫ Employs PFM to deliver 3.
3 V/40 µA while drawing less than 50 µA from VIN of 12 V ▫ Operates down to at least 3.
6 VIN • Adjustable 1.
5 A/±1.
5% asynchronous buck regulator with an integrated 120 mΩ high-side MOSFET (SW2) • Adjustable 2.
0 A/±1.
5% asynchronous buck regulator with an integrated 110 mΩ MOSFET (SW3) • Adjustable ±1.
5% synchronous buck controller with integrated gate drivers and current sensing (SW4) • Fixed 425 kHz, interleaved PWM switching frequency • EN/SYNC input for PWM frequency scaling • Adjustable soft-start time for each switching regulator • All switching regulators provide pre-bias startup with zero reverse current • All switching regulators have overvoltage protection • External compe...
