When debugging PSoC6 BLE, I encountered abnormal voltage between LDO and BUCK. The specific phenomena are as follows:
Buck mode Testing Data:
1. The normal voltage of VDD_NS and VDDD is 3.30v;
2.VDCDC is 1.94v;
3. DVDD is 1.58 V
4. VCCBUCK1 is 1.69 V
5.VDDR1, VDDR2 and VDDR3 are 1.93v
6. VDDR_HVL is 2.30 V.
7. VCCD is 1.69 V
LDO mode Testing Data:
1. The normal voltage of VDD_NS and VDDD is 3.30v;
2.VDCDC is 1.99v;
3. DVDD is 1.58 V
4. VCCBUCK1 is 1.63 V
5.VDDR1, VDDR2 and VDDR3 are 1.83v
6. VDDR_HVL is 2.28 V.
7. VCCD is 1.66 V
- The hardware circuit is as follows:
The software configuration is as follows
Note: the code works well in the development version, but the MCU package is switched.)
