Do Ψjt, θja, and power dissipation vary by the size of the board? How can I predict the power dissipation, the Ψjt, and the θja of the board we have designed?

 What is the difference between forced PWM and normal PWM? Which type of PWM control device should I choose in what case?

 What is the function of the ASO protection circuit (Over Voltage Protection: OVP) of NJM2386?

 What does 'SSCG(SSFM)' stand for? What can be expected from SSCG?

 When the input voltage was raised steeply from a low value, the output of the DC/DC converter may overshoot. Why did this happen? How should I take measures against this problem?
