TSOT23-6 NEX80806 Adaptive multi-mode flyback controller Rev. 2 — 28 October 2024 Product data sheet 1. General description The NEX80806 is an intelligent multi-mode PWM controller implemented with peak current mode control. As the load changes, it automatically switches mode between Continuous Conduction Mode (CCM), QuasiResonant (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. A peak load mode is implemented to support a peak output current requirement in a short period, which is normally required in power supply of PC, printer, etc.
