Description

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.

LA4906 datasheet

Description

The LA4906 is a BTL two-channel power amplifier for use in car audio systems. It uses a signal-following switching technique in the power supply for the amplifier output stage and a newly-developed nonlinear amplifier that features nonlinear characteristics in the signal system. These features hold increases in the number of external components to a minimum, and reduce power dissipation (and thus heat generation) in the practical operating region to about 1/2 that of earlier class B amplifier ICs.

Features

1. Power dissipation reduced by 50% (for music at average power levels, as compared to earlier Sanyo products)
2. The number of required signal-following switching circuits has been reduced to just one circuit for two
channels, reducing the number of external components.
3. The output is a pure analog signal; no switching noise whatsoever appears on the output lines.
4. Built-in standby switch
5. Clipping detection function
