Part Number: TPS61087

how to choose the overvoltage protection circuit zener and resistor?what'S the principle of the design?

in my use BZX84C15 wos used,when IOUT is large,Vout is not stable,only small current  is OK,why must use BZX84C18,the output is only 15?

  • Dear Sir,

    When Vo set to 15V, the protection circuit must be higher than 15V, or it will disturb the normal working. So 18V is a good choice.

    Best Regards,
