Thanks to current-mode control, the NCP1200 drastically simplifies the design of reliable and cheap offline converters with excellent audio- susceptibility and inherent pulse-by-pulse control. When the current setpoint falls below a given value, e.g. the output power demand diminishes, the IC automatically enters the so-called skip cycle mode ...

They are as follows: Loop gain and phase – determines the stability of your design, and available margin to accommodate variations in components. Output impedance – determines the output regulation, dynamic load response, and susceptibility to complex loading. Audiosusceptibility – determines the transmission of noise from input to output.

SWITCHING POWER SUPPLY DESIGN REVIEW
https://www.ti.com/lit/ml/slup072/slup072.pdf
The flyback, when compared to other switching regulator topologies, has several cost and performance advantages: Cost Advantages: 1. For output power levels less than -150W, the design of the power transformer (coupled inductor) is relatively simple. 2. Assembly costs for the flyback regulator are low due to a low overall component count.
