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擄C

to +85擄C) as well as commercial temperature grade (-10擄C to

+85擄C)
