Manufacturer: STMicroelectronics

Overview: VIPERGAN50 Datasheet Advanced quasi-resonant offline high voltage converter with E-mode GaN HEMT Product status link VIPERGAN50 Product label Figure 1.

General Description

The VIPERGAN50 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 50 W in wide range.

It integrates a complete set of

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-forwar.
