no pwm fan

Ashutosh Nahar

hi,

I need to design a control circuit for No-PWM fan which should vary the speed of the fan base on supply voltage to the Fan.

Please help me and suggest some part.

Hello ASHU,

What kind of motor (AC or DC, type) does the fan have and what are its specifications?

Hello Ashu,

I haven't heard back from you so I assume you found what you needed. If your fan does use a DC motor, please check out this speed control http://www.ti.com/analog/docs/litabsmultiplefilelist.tsp?literatureNumber=sboa043&docCategoryId=1&familyId=3523 and also search our website using keywords "motor speed control" for additional info.
