Overview
The VIPER53EDIP-E, produced by STMicroelectronics, is a highly integrated offline power supply controller that combines an enhanced current mode PWM controller with a high voltage MDMesh Power MOSFET in the same package. This device is designed for offline power supplies with a wide range of input voltages and offers several key benefits, including efficient standby mode, overload and short-circuit protection, and high voltage start-up current source. It is particularly suited for applications requiring up to 50W in single European voltage range or up to 30W in wide range input voltage for the DIP-8 package, and up to 65W in single European voltage range or up to 40W in wide range input voltage for the PowerSO-10 package.
