Description
The FAN5069 combines a high efficiency PWM controller and a
LDO (Low DropOut) linear regulator controller. Synchronous
rectification provides high efficiency over a wide range of load
currents. Efficiency is further enhanced by using the low-side
MOSFET's R
DS(ON)
to sense current.
Both the linear and PWM regulator soft-start are controlled by a
single external capacitor, to limit in rush current from the supply
when the regulators are first enabled. Current limit for PWM is
also programmable.
The PWM regulator employs a Summing-Current-Mode control
with external compensation to achieve fast load transient
response and provide system design optimization.
FAN5069 is offered in both industrial temperature grade (-40°C
to +85°C) as well as commercial temperature grade (-10°C to
+85°C)
