NEX80605DAZ is a NEX806 series wide Vcc range quasi-resonant flyback controller. It is a high-frequency quasi-resonant PWM controller implemented with peak current mode control. As the load changes, the NEX806 device automatically switches mode between 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 conditions. Furthermore, spread spectrum and smart driving functions can minimize noise and improve EMI performance. Applications include USB PD/QC chargers, AC/DC adapters for portable devices, and auxiliary power for industrial and home equipment.

• Wide VCC range (10V-83V) supports PD/PPS
• Direct GaN driver, valley switching operation in QR/DCM/PFM
• Burst mode with ultra-low operation current in light load and no load
• Internal soft start (SST), output overvoltage protection (OVP), overload protection (OLP)
• Spread spectrum for better EMI, internal over temperature protection (OTP), CS open/short protection
• External OTP by NTC resistor, VCC over/under voltage protection (VCC OV/UV)
• Line voltage brown-in /brown-out (BNI/BNO), output short circuit protection (SCP)
• Secondary rectifier short protection (SRSP), overpower protection (OPP) to meet LPS
• TSOT23-6FC package
• Temperature range from -40°C to +125°C
