Part Number: LTA803N
Function: LCD power management chip IC, PFC and flyback controller
Package: SOP 16 Pin
The LTA803N is the third generation of green Switched Mode Power Supply (SMPS) controller ICs. The LTA803N combines a controller for Power Factor Correction (PFC) and a flyback controller. Its high level of integration allows the design of a cost-effective power supply with a very low number of external components. The special built-in green functions provide high efficiency at all power levels. This efficiency applies to quasi-resonant operation at high-power levels, quasi-resonant operation with valley skipping, as well as reduced frequency operation at lower power levels. At low-power levels, the PFC switches off to maintain high efficiency.
