Description
The FAN5234 PWM controller provides high efficiency
and regulation with an adjustable output from 0.9V to
5.5V required to power I/O, chip-sets, memory banks, or
peripherals in high-performance notebook computers,
PDAs,
and
internet
appliances.
Synchronous
rectification and hysteretic operation at light loads
contribute to a high efficiency over a wide range of
loads. The Hysteretic Mode of operation can be
disabled if PWM Mode is desired for all load levels.
Efficiency is further enhanced by using the MOSFET’s
RDS(ON) as a current-sense component.
Feed-forward ramp modulation, average current mode
control, and internal feedback compensation provide
fast response to load transients. The FAN5234 monitors
these outputs and generates a PGOOD (power-good)
signal when the soft-start is completed and the output is
within ±10% of its set point. A built-in over-voltage
protection prevents the output voltage from going above
120% of the set point. Normal operation is automatically
restored when the over-voltage conditions cease.
Under-voltage protection latches the chip off when the
output drops below 75% of its set value after the soft-
start sequence is completed. An adjustable over-current
function monitors the output current by sensing the
voltage drop across the lower MOSFET.
