MAX8775
Key Features
- It is intended for GPU cores and I/O power generation in battery-powered systems
- Flexible configuration allows the MAX8775 to operate as two independent single-phase regulators, or as one high-current two-phase regulator
- The REFIN voltage setting allows for multiple dynamic output voltages required by the different GPU operating and sleep states
- Automatic fault blanking, forced-PWM operation, and transition control are achieved by detecting the voltage change at REFIN
- Current-mode control allows the use of low-ESR output capacitors
- Internal integrators maintain high output accuracy over the full line-and-load range, in both forced-PWM mode and pulse-skipping mode
- True differential current sensing provides accurate output current limit and current balance when operated in bined mode
- Independent on/off and skip control allows flexible power sequencing and power management
- Voltagecontrolled soft-start reduces inrush current
- Soft-stop gradually ramps the output voltage down, preventing negative voltage dips
