DescriptionThe FAN5230 is a high efficiency 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 rectification 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 efficiency 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.
A single Power-Good signal is issued when soft start is
completed and all outputs are within ± 10% of their settings.
