The TL103Wx devices combine the building blocks of a dual operational amplifier and a fixed voltage reference – both of which are often used in the control circuitry of switch-mode and linear power supplies. OP AMP1 has the noninverting input internally tied to a fixed 2.5V reference, while OP AMP2 is independent, with both inputs uncommitted.
The upgraded TL103WB features improvements such as a wider supply range (up to 36V), lower supply current (275µA/amp) and tighter voltage regulation. This regulation can be achieved through low offset voltages for both operational amplifiers (0.3mV typical) and tight tolerances for the voltage reference (0.44% at 25°C and 1.04% over operating temperature range).
The TL103WB has a widened temperature range of –40°C to 125°C.

When input power factor is necessary (like LED lighting, avionics or low THD application as well as the isolation), the single stage PFC Flyback is the best topology. The only drawback of such topology is the 100Hz/120Hz voltage ripple on output.
This reference design is an offline isolated flyback. The AC-DC power stage is based on the UCC28750 fixed-frequency peak current mode controller, which features continuous conduction mode (CCM) and discontinuous conduction mode (DCM) modulation, as well as secondary-side regulation. Frequency (...)
