VIPERGAN100
Description
The VIPERGAN100 is a high voltage converter, designed for medium power quasiresonant ZVS (Zero Voltage Switching at switch turn-on) flyback converters, capable to provide an output power up to 75 W in wide range and up to 100 W in European range or with a PFC in the front end. It integrates a complete set of features that provide an extremely flexible and easy to use chip and helps to design a highly efficient offline power supply.
Key Features
- Quasi-resonant (QR) flyback controller
- 650 V E-mode power GaN transistor
- Embedded sense FET
- Dynamic blanking time and adjustable valley synchronization delay functions, to maximize efficiency at any input line and load condition
- Valley-lock to ensure constant valley skipping
- Advanced power management for less than 30 mW standby power consumption with adaptive burst-mode
- Output OVP protection
- Input voltage feed-forward compensation for mains independent OPP variation
- Brown-in and brown-out protection
- Input OVP protection
