NEX80611DA
Description
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.
Key Features
- Wide VCC range (10 V-83 V) supports PD/PPS
- Direct GaN driver
- Valley switching operation in QR/DCM/PFM
- Burst Mode with ultra-low operation current in light load and no load
- 130 kHz or 170 kHz 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
