General Description
The APW7088, two-phase PWM control IC, provides a precision voltage regulation system for advanced graphic microprocessors in graphics card applications. The integration of power MOSFET drivers into the controller IC reduces the number of external parts for a cost and space saving power management solution.
The APW7088 uses a voltage-mode PWM architecture, operating with fixed-frequency, to provides excellent load transient response. The device uses the voltage across the DCRs of the inductors for current sensing. Load line voltage positioning (DROOP), channel-current balance and over-current protection are accomplished through continuous inductor DCR current sensing.
