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 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.
