LT3798

Isolated No Opto-Coupler

Flyback Controller

with Active PFC

FEATURES

DESCRIPTION

ꢀhe Lꢀ^®3798 is a constant-voltage/constant-current iso-

lated flyback controller that combines active power factor

correction (PFC) with no opto-coupler required for output

voltage feedback into a single-stage converter. A Lꢀ3798

baseddesigncanachieveapowerfactorofgreaterthan0.97

by actively modulating the input current, allowing compli-

ance with most Harmonic Current Emission requirements.

Isolated PFC Flyback with Minimum Number of

External Components

V and V

Limited Only by External Components

OUT

Active Power Factor Correction

Low Harmonic Distortion

No Opto-Coupler Required

Constant-Current and Constant-Voltage Regulation

Accurate Regulated Voltage and Current (±±5 ꢀypical)

Energy Star Compliant (<0.±W No Load Operation)

ꢀhermally Enhanced 16-lead MSOP Package

ꢀhe Lꢀ3798 is well suited for a wide variety of off-line

applications. ꢀhe input range can be scaled up or down,

depending mainly on the choice of external components.

Efficiencies higher than 865 can be achieved with output

powerlevelsupto100W.Inaddition,theLꢀ3798caneasily

be designed into high DC input applications.

APPLICATIONS
