ISL9502 Overview
® ISL9502 Data Sheet July 17, 2006 FN9275.1 Two-Phase PWM Controller for Graphics Processor Units (GPU) Increase in GPU clock frequency is acpanied by associated increase in the demand for power and transientcurrent slew rate. At the same time, the voltage tolerance requirement during steady-state and transient operation is being more stringent of advanced GPU. The ISL9502 is a two-phase PWM controller with embedded...
