To overcome the disadvantages inherent in both circuits, you can use an SMPS to maintain high efficiency and a low-dropout regulator to reduce the output noise and ripple voltage of the SMPS. Setting ...

The NXP TEA172x family is a series of small, low-cost module SMPS controller ICs that operate directly from the rectified universal mains input and are tailored for low-power ...

The low-power (milliwatt) flyback transformer used in a switched-mode power supply (SMPS) needs to be designed with a gap in the magnetic path for maximum power delivery over temperature.
