LM5013-Q1: Minimum Input Voltage

Masakazu Adachi

Part Number: LM5013-Q1

Hello team,

I have a question.

How should the minimum input voltage be calculated? I know how to calculate the maximum input voltage from equation 9.

Regards,

Hello

You can use the following approximate equation:

Vin-min = Vout/(1-(Toff*Fsw))

You can assume Toff = 50ns.

This equation is approximate. If the calculation gives a Vin-min

less than 6V, then 6V is the minimum.

Thanks
