In the sleep mode, MCU controls the 5V_ON foot to pull down the EN foot. When the EN foot is at 0, the output voltage is still about 2.5V, and the power cannot be turned off.
Any advise?thanks in advance

Hi CS:
Is there other power supply in your circuit?
And please share the waveform of Vin, Vout, EN, L1, L2 with us. Thank you!
