FAN5231 Description
The FAN5231 is a highly integrated power controller, which provides a plete power management solution for mobile CPUs. The IC integrates two PWM controllers and a linear regulator as well as monitoring and protection circuitry into a single 28-lead plastic SSOP package. The two PWM controllers regulate the microprocessor core and I/O voltages with synchronous-rectified buck converters, while the linear regulator...
