NEX80809DAZ

NEX80809DAZ is a wide Vcc range multi-mode flyback controller. It is an 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 conditions. Furthermore, the spread spectrum and smart driving function 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 to 83V) supports PD/PPS, multimode support CCM/QR/DCM/PFM
• Valley switching operation in QR/DCM/PFM, internal soft start (SST)
• Burst mode with ultra-low operation current under light load and no load
• Output overvoltage protection (OVP), spread spectrum for better EMI
• Internal over temperature protection (OTP), 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), CS open/short protection, overload protection (OLP)
• Secondary rectifier short protection (SRSP), overpower protection (OPP) to meet LPS
• TSOT23-6FC package
• Temperature range from -40°C to +125°C
