†
Notes:
1) Frequency set to 275 kHz by R3.
2) This unit and the components are thermally rated to 2.5 A. The output current should not exceed 2.5 A unless
proper thermal management is put in place.
3) DO NOT change the set output voltage jumper (JP1) while power is applied to the unit.
† Input voltage range for 3.3 V output. When using 5-V output, minimum input voltage must be greater than 5.5 V.
