LT1170 Buck Converter

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.
