LM5001-Q1: LM5001-Q1 design question

user5913722

Part Number: LM5001-Q1
Other Parts Discussed in Thread: TPS61170-Q1, TPS61170, LM5000

My use case: input: 10v-14v, output:65V, output current < 20mA.

Can i use LM5001-Q1 boost mode? webench show that input voltage is not in range.

Hi,

I cannot see your picture. But yes. Use a DAC connected to FB to adjust Vout is a good idea.
