NEX806 series
Wide Vcc range quasi-resonant flyback controller
The NEX806 device series (NEX806xx) are high frequency quasi-resonant PWM controllers 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 condition.
The wide 10 V to 83 V VCC range makes NEX806xx devices suitable for wide output voltage range applications, such as USB PD/PPS which require an output range between 3.3 V to 21 V .
The NEX806xx 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, spread spectrum and smart driving functions can minimize noise and improve EMI performance.
The NEX806xx device series comes in a cost-effective TSOT23-6 package.
