3.3 Volts is generated inside the OSD3358 by a TI TPS65217C PMIC die PMIC stands for Power Management IC You can read the TI data sheet on the TPS65217C But the OSD3358 is a multi-chip module, so not too much you can do, other than replace the entire OSD3358, if damaged. And that would require BGA (Ball Grid Array) rework capability. --- Graham
