High-voltage GaN converters
Up to 100 W of output power to make GaN more accessible
The VIPerGaN series of high-voltage converters are designed for medium-power quasi-resonant zero voltage switching (ZVS) flyback converters. The devices can provide up to 100 W output power over a wide range.
The complete set of integrated features ensure extreme flexibility and ease of use in high efficiency offline power supply designs. The ZVS quasi-resonant operation with dynamic blanking time and valley synchronization reduces switching losses and maximizes overall efficiency at any input line and load condition. The advanced power management with low quiescent helps achieve low standby consumption. The feedforward compensation minimizes variation of output peak power over the entire input voltage range.
The devices include output overvoltage, overtemperature, and overload protection to considerably increase end-product safety and reliability. The device also integrates brown-in/-out protection and input overvoltage protection (iOVP) protects the system from abnormal rises on the input line. All the protections are in autorestart mode.
