NEX80605DA

NEX80605DA Production

Wide supply voltage range quasi-resonant flyback controller, 130 KHz, 11.5 V gate driver with Over Current Protection (OCP)

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.

Interactive datasheet

How does it work?

The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
