TSOT23-6FC NEX8080 series Wide Vcc range multi-mode flyback controller Rev. 1 — 30 September 2024 Product data sheet 1. General description The NEX8080 device series (NEX8080x) are intelligent multi-mode PWM controller implemented with peak current mode control. As the load changes, it automatically switches between Continuous Conduction Mode (CCM), Quasi-Resonant (QR) mode, Discontinuous Conduction Mode (DCM) and Pulse Frequency Modulation (PFM) Mode to maintain a high efficiency across the entire load range. To achieve an ultralow standby power, Burst Mode (BM) is implemented in very light load or no-load condition. The wide 10 V to 83 V VCC range makes NEX8080x devices suitable for wide output voltage range application, such as USB PD/PPS which require an output range between 3.
