STMicroelectronics 8-Pin SOIC PWM Controller 60 kHz, 50V, Current Mode VIPER12ASTR-E

STMicroelectronics VIPER12ASTR-E PWM Controller is an 8-pin SOIC package device optimized for high-voltage off-line converters. It integrates a current mode PWM controller and a 700V vertical power MOSFET, designed for efficient switching at a frequency up to 60 kHz. Operating at a maximum supply voltage of 50V, this device delivers output voltages up to 730V with an output current of 480 mA.

The device has a low start-up supply current of 1 mA and a supply current of 5 mA during normal operation, contributing to energy efficiency in power supply designs. With dimensions of 5 mm length, 4 mm width, and 1.65 mm height, it supports surface mounting, facilitating compact PCB designs.

This PWM controller is suitable for applications such as offline power supplies, AC/DC converters, and other power management systems requiring precise power regulation. It ensures reliable operation over a wide temperature range from -40°C to 150°C, making it robust for industrial and commercial electronic applications.

The device allows a maximum duty cycle of 16%, which balances power output and thermal management. It meets JESD97 and ECOPACK standards, guaranteeing compliance with industry quality and environmental regulations.

Part of the VIPer12A series, the VIPER12ASTR-E offers stable PWM controller solutions with enhanced integration of power MOSFETs, suitable for a broad range of power management IC requirements without automotive certification.
