Description
The FAN5069 combines a high-efficiency Pulse-Width-
Modulated (PWM) controller and an LDO (Low DropOut)
linear regulator controller. Synchronous rectification pro-
vides high efficiency over a wide range of load currents.
Efficiency is further enhanced by using the low-side
MOSFETs R
DS(ON)
to sense current.
Both the linear and PWM regulator soft-start are con-
trolled by a single external capacitor, to limit in-rush cur-
rent 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 design optimization.
FAN5069 is offered in both industrial temperature grade
(-40癈 to +85癈) as well as commercial temperature
grade (-10癈 to +85癈).
