The Renesas is a Continuous Conduction Mode (CCM) PFC controller IC designed to improve power efficiency and reduce harmonics in AC/DC power supplies. Application: PFC controller (CRM/CCM). Package: Usually 16-pin SOP (16SOP).

If the output voltage drops due to an increased load, the voltage at the error amplifier's inverting input drops below the reference voltage. The amplifier responds by increasing its output voltage, driving the base of the pass transistor harder. The transistor opens up, allowing more current to flow, driving the output voltage back up to its designated set point. Short-Circuit and Overcurrent Protection
