Hii Experts,
I have purchase LT1170 IC and i have Design PCB Board using datasheet Circuit Diagram.
I am giving Vin=32V and i am set Vout=12V but i am getting Vout= 29V i the circuit i am attaching my schematic diagram.
I have design circuit same in datasheet.
Please help me in this issue
Hi manoj1996,
in the attached circuit diagram, R6 and R7 are designed for an output voltage of approx. 5V. The reference design is not intended for an output current lower than 100mA. If in your measurement only R9 and LED3 draw some current, the output current is certainly below 100mA. Try increasing the output current above 100mA and measure the output voltage again.
Regards Michael
