Presentation transcript:

Behavior of DC/DC converter at power off(not TI device) In case of not TI device When power is off, 24V input is lower. EN is connected with Vin. If the ramp rate is very slow, on duty is higher before UVLO acvite, output 5V become unstable like an oscillation. In this case, the device is disabled by using EN pin before the phenomenon happened. The customer wants to know the case of LM43603. Is there any possibility of this phenomenon? Vin:24V Vout:5V Iout:2.2Amax Ramp down voltage is not sure. Schematic and BOM: see attached file of 24Vin5Vout2.2A webench_design Vin Vout
