XL1509-ADJ feedback resistor calculator
XLSEMI XL1509-ADJE1, UMW (Youtai Semiconductor) XL1509-ADJ
Select the ideal feedback resistors for your DC converter circuit. This tool helps you adjust the output voltage of a XL1509-ADJ DC/DC converter. Experiment with combinations of up to three resistors, enhancing precision in voltage regulation.
Datasheet note:
Select R1 to be approximately 1K, use a 1% resistor for best stability. C1 and CFF are optional; in order to increase stability and reduce the input power line noise, CIN and C1 must be placed near to PIN1 and PIN5~8; For output voltages greater than approximately 10V, an additional capacitor CFF is required.
