This is a Technical question regarding the APD3367 regulator IC. We have incorporated your IC in our circuit & have tested many times. It is running as per the Datasheet. Recently we have encountered one issue & We want your clarification regarding it.
We have one circuit where the IC will convert 15 V input to 3.3 V output & We need 30 mA output current. Initially we were using TRACO POWER TSR 0.5-2433 IC for this purpose. The current consumption was 24 mA with Traco Power IC.
Now We soldered ADP3367 smd IC & the current consumption increased to 66 mA. The IC started to heat up & output of 3.3 V is also not achievable. This happened several times & but every time the same result. Kindly guide us regarding this issue. Why current is increasing everytime when we are replacing Traco IC with your ADP3367 IC. Help & Support is needed.
It is strange that your current consumption (Ignd) reaches 36mA (Ignd=Iin-Iload) when the datasheet limit is 14mA max. Your headroom (VIN − VOUT) is also very high (11.7 V) which will…
Hi, Nitesh.It’s good to know that your circuit is working now.
The 100mA output current you are getting in ADP3367 linear regulator is nearly the same with the Traco IC switching regulator as shown below…
Hi, Nitesh.Here are some thoughts/suggestions you might consider in your circuit.
