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 comprehensive 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 comes in a cost-effective TSOT23-6 package. Figure 1. Typical application
