LT3798EMSE#PBF General Description

The LT3798 is a constant-voltage/constant-current isolated flyback controller that combines active power factor correction (PFC) with no opto-coupler required for output voltage feedback into a single-stage converter. A LT3798 based design can achieve a power factor of greater than 0.97 by actively modulating the input current, allowing compliance with most Harmonic Current Emission requirements.

Key Features

Isolated PFC Flyback with Minimum Number of External Components
V_IN and V_OUT Limited Only by External Components
Active Power Factor Correction
Low Harmonic Distortion
No Opto-Coupler Required
Constant-Current and Constant-Voltage Regulation
Accurate Regulated Voltage and Current (±5% Typical)
Energy Star Compliant (<0.5W No Load Operation)
Thermally Enhanced 16-lead MSOP Package

Application

Offline 5W to 100W+ Applications
High DC V_IN Isolated Applications
Offline Bus Converter (12V, 24V or 48V Outputs)
