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 3.3 V to 21 V. The NEX8080x offers prehensive protection including output OV/UV, VCC OV/UV, OPP, 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 noise and improve EMI performance. The NEX8080x device series es in a cost-effective TSOT23-6 package. L EMI filter NEX8080x GND DRV 2. Features and benefits - Wide VCC range (10 V to 83 V) supports PD/PPS - Multimode support CCM/QR/DCM/PFM - Peak Load Mode (NEX80805) - Valley switching operation in QR/DCM/PFM - Burst mode with ultra-low operation current under light load and no load - 65 k Hz or 85 k Hz maximum frequency options - Internal soft start (SST) - Output over voltage 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...
