Dears:
Could you kindly help to check the below schematic?
Since the input is 12v, and the signal of EN, PWM is normal.
And setting the I is 100mA, output is 27v, switching frequency is 450KHz, however, the output is 16v.
Why the output value can not be 27v?
Pls. kindly help to give some advice about the issue.
Many thanks!
Best regards
Luck Wu
