The power-on sequence of an MCU (Microcontroller Unit) is a carefully designed sequence that ensures the chip reliably transitions from a completely powered-off state to normal operating conditions. 1. Power-on Reset When power is applied to the MCU, the supply voltage rises from 0V to the rated operating voltage (e.g., 3.3V). The internal reset circuit … Read more
ROHM Semiconductor has developed a new reference design that uses a single microcontroller (MCU) to simultaneously control both sides of an AC-DC power supply, namely the power factor correction (PFC) AC-DC converter stage and the flyback DC-DC converter stage. ROHM states that by using a single controller to support two power stages, it can reduce … Read more
