System Electronics Regulator For Mobile PCs

The FAN5230 is a high efciency and high precision multiple-output voltage Regulator for notebook PC and other similar battery-powered applications. It integrates three pulse-width modulated (PWM) Switching Regulator controllers and two linear Regulators to convert 5.4V-to-24V notebook battery power into the voltage used by the circuitry that surrounds the Microprocessor in these systems. The two primary PWM Controllers in the FAN5230 use synchronous-mode rectication to provide 3.3V and 5V at over 5A each. They Switch out-of-phase to minimize input ripple-current. Utilization of both input and output voltage feedback in a current-mode control allows for fast and stable loop response over a wide range of input and output variations. PWM control in normal operation and hysteretic control under light load provides efciency of greater than 95% over a wide range of input and output variations. The third PWM Controller generates 12V at 120mA. A propri- etary technology is used for accurate [ 1%] sensing of out- put current using the RDS(ON) of the external MOSFETs eliminating external Current Sense resistors which saves board space and reduces BOM cost. Two integrated linear Regulators provide stand-by ALWAYS- ON power at 3.3V and 5V for light (50mA) loads. Additional FAN5230 features include over-voltage, under-voltage, and over-current monitors and thermal shutdow protection. By Fairchild Semiconductor
