Tool/software:
Hello,
I am experiencing an issue with DCR011230U package IC.Which is DCR01 Series, 1-W, 1000-VRMS Isolated, Regulated DC/DC Converter Module.
The DC-DC converter is not providing the expected 3.3V output despite a stable 12V input.
We connected circuit was like below,
DCDC DCR011203
Pin 1 ,2 : Vs+
Pin 26 ,27 : Vs-
Pin 12 : VREC
Pin 13 : -Vout
Pin 14 : +Vout
Pin 15 : NC : Not connected
Pin 16 :ENABLE
Pin 17 : Error
Pin 28 : SYNC : not connected
Pin 1 ,2 and 26,27 are connected to 12v and GND with 0.1uF capacitor
VREC and EN are shorted and one 1uf filter capacitor is between VREC and -VOUT.
10-kΩ resistor between the ERROR pin and the output voltage(+VOUT).
We given one output load resistor which is 220R and one capacitor value is 0.1uf to +VOUT and -VOUT.
- Input volatage : 12V
- Expected output voltage: 3.3V
- Actual Output Voltage: 100mV - 200mV
I am looking for troubleshooting advice or potential causes for why the DC-DC converter is not producing the correct 3.3V output despite a stable 12V input.
