NEX80806
Adaptive multi-mode flyback controller
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), 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.
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.
The NEX80806 offers comprehensive protection including output OV/UV, VCC OV/UV, OCP, line voltage BROWN-IN/OUT, secondary SR short, CS open/short, internal/external OTP, etc.
Furthermore, the spread spectrum and smart driving function can minimize the noise and improve EMI performance.
The NEX80806 comes in a cost-effective TSOT23-6 package.
